Causes Of Uti’s In Cats
Bacteria causes urinary tract infections when it enters a cat’s bladder. Typically bacteria enters a bladder through a cat’s urethra, which is the path urine takes from the bladder to exit the body. Once in the bladder, bacteria grow and reproduce to create more bacteria and infiltrate this once sterile space. Simple things like a dirty litter box, dirty bed, or an overall dirty environment that a cat spends time in can allow bacteria to enter a urethra and cause a urinary tract infection.
How And Why Urinary Tract Infections Occur
UTIs can develop in any pet. A common reason they develop in cats is because of poorly balanced diets or environmental factors such as stress. Some cats are naturally predisposed to UTIs, like older female cats or cats with diabetes. With pets who get UTIs more frequently, youll notice the symptoms sooner and become accustomed to the treatments that work well, but UTIs should always be taken seriously.
While your cat cant tell you what they feel, common physical symptoms of a UTI include fever, backache, painful and frequent urination, and lethargy. Causes could be related to diet, but may also include immunological deficiency or fungal or protozoan infections. Other causes could be bladder stones, injuries, or tumors.
Potential Side Effects Of Amoxicillin For Cats
Antibiotics, including amoxicillin, can cause a range of side effects for cats. Since every cat is an individual, each cat will respond differently to amoxicillin. PetCareRX mentions the following as the most prevalent side effects to antibiotics: rashes, fever, kidney or liver damage, diarrhea and vomiting.
Also, antibiotics can be particularly difficult on the digestive system, so confirm if your cat should take amoxicillin with or without food.
In addition, Vetinfo indicates that your cat could have dangerous complications if amoxicillin is taken while other antibiotics are in his system. And some cats are allergic to it. Monitor your cat closely while taking any medications, and alert your vet to anything out of the ordinary; health or behavior wise.

Best Practices For Amoxicillin Usage For Cats
As with all medications, it is important to follow all the labeled directions. This includes sticking to the timetable for giving it that your veterinarian has prescribed. Liquid amoxicillin needs to be kept in the refrigerator except when you are giving it to your cat.
If you miss a dose, give it to your cat unless it’s almost time for the next dose. In that case, you can skip the missed dose. Doing so frequently can make the medication ineffective. It can also cause bacterial resistance to develop.
It is important to keep in mind that some infections may not be bacterial. It is also important to remember that amoxicillin is a medication. As such, never self-prescribe the medication to your cat, even if you are a medical doctor.
Are Weak Legs A Cat Uti Symptom
Urinary tract infections and other forms of urinary tract disease will not paralyze or weaken your cats legs. However, some cats may take on an odd gait or hold their bodies differently due to the pain of FLUTD.
If the disease is left untreated for a day or more, your cat may feel extremely fatigued and might not be able to walk normally.

Cats Are Obligate Carnivores And Have No Physiological Requirement For Carbohydrates Which Are Kibble Diet
Your veterinarian may recommend special prescription diets to help dissolve the stones, but make sure to continue reading for other natural remedies to help your cats crystal issue if this is occurring, because many of these diets are kibble which is a root cause for your cats urine problems in the first place.
The crystals and inflammatory changes are what can lead to sludgy debris that can lead to a urinary obstruction, especially in male cats whose urethras are not as wide as a females urethra.
So if youre seeing your cat, especially male cat, go in and out of the litter box but not product any urine or very little urine, this is a symptom of a urinary tract infection and urinary blockage.
You must go to the vet right away since this is an emergency.
How Is Flutd Diagnosed
Because FLUTD has many causes, it can be difficult to diagnose. Based on your cat’s symptoms, your veterinarian will do a physical examination and most likely will run a urinalysis assessing urine pH and concentration and presence of crystals, bleeding, inflammation and infection. If the cause is still not identified, tests such as urine culture, x-rays, blood work and additional urine tests may be recommended.

Why Is My Cat Going To The Litter Box Every Few Minutes
Cats with urinary tract infections or other forms of urinary tract disease spend a lot of time going in and out of the litter box. It might look like your cat is constipated, but if you watch closely, youll notice that theres not a lot of moisture in the box.
Frequent trips to the litter box indicate that your cat needs relief but cant get everythingor anythingout. If your cat keeps trying to pee but only a little comes out, its a sure sign that something is wrong. Bring him or her to the veterinarian as soon as possible.
If your cat keeps going to the litter box but nothing happens at all, he or she may be dealing with a complete urethral blockage. In this case, seek emergency veterinary care immediately. Just a few hours of hesitation could be fatal.
Recovery And Management Of Urinary Tract Infection In Cats
The recovery period depends on the severity of the UTI and how quickly the cat was treated. If the infection is caught early on, and there are no other developments as a result, a full recovery should be expected within a few days or so of beginning antibiotic therapy. Some cats seem markedly improved after even one dose of antibiotics. However, ALWAYS complete the full course of medications exactly as directed by your veterinarian.
Occasionally, cats will develop frequent, recurrent urinary tract infections. In these cases, a longer course of antibiotics and repeat urine cultures may be necessary.

Signs Of A Urinary Tract Infection In Cats
Symptoms of UTIs in cats are similar to cystitis, since both conditions cause general discomfort in the urinary system. It is important to note that not all cats show symptomsin one study of cats with a UTI, 35 percent of cats showed no signs .;
Below are the symptoms you might see:
- Urination outside of the litter box
- Change in frequency of urination
- Straining to urinate
- Vocalizing while urinating
- Change in color of the urine
- Increased drinking
- Increased volume of urine
- Change in normal behaviors for example, hiding or eating less
- Licking genitalia more frequently
- Discharge from the vulva or prepuce
What Causes Utis In Cats
In general, urinary tract infections develop when the urethra becomes contaminated with bacteria that normally colonize the rectum and surrounding area. Once in the urethra, the bacteria migrate upstream and take up residence in the bladder.
The presence of mineralized bladder stones or crystals in the urine may also be a cause of UTIs. Because the crystals are hard and irritating to the bladder, theres a greater risk for infection.

Bacterial Growth And Susceptibility Testing
Bacterial growth was observed in 5 of 20 urine samples of female cats and in 11 of 41 samples of male cats . Three in five cats with bacterial LUTI were 1;year old or younger, 9/38 27 years old and 4/18 8;years old or older . In this study, no significant difference was found between female and male cats with bacterial LUTI . The differences among age groups were also not significant .
Antimicrobial susceptibility tests results showed that 13 of 16 isolates were susceptible to cefovecin. E. avium and S. epidermidis isolates were resistant and Arcanobacterium renale isolate was intermediate.

Why Is My Cat Lying In The Litter Box
If your cat has been lying in the litter box a lot lately, it might point to stress or illness, but its not always a sign of urinary tract issues. In addition to lying in the litter box, cats with UTIs or other urinary problems will strain, lick at their genitals, hide, meow in the box, and look restless.
If your cat is lying in the litter box and also exhibiting these behaviors, theres a good chance that a UTI or other urinary tract issue is to blame.
Among cats with urinary tract problems, this behavior appears to result from a mix of stress and, perhaps, a need to stay in the box just in case something changes. Imagine feeling like you had to urinate for hours but couldnt get everything outwouldnt you stay near the toilet?
Diagnostic Vs Therapeutic Urine Cultures
What are diagnostic urine cultures?
- Quantitative urine cultures before initiating antibiotic therapy is considered to be the gold standard for diagnosis of bacterial urinary tract infections .
- Diagnostic urine cultures provide accurate identification of specific bacterial species and aid;in the selection of antibiotics. It also facilitates differentiation of recurrent UTIs caused by relapses from recurrent UTIs caused by reinfections.
- If a patient is currently being treated with an antibiotic, it should be discontinued for three to five;days before diagnostic urine culture to minimize inhibition of bacterial growth.
What are therapeutic urine cultures?
- Culture of urine at strategic times during antibiotic therapy is an effective method of assessing therapy. Therapeutic cultures are essential for determining why a patient may not be responding to treatment.
- For patients with a high risk of morbidity and mortality , evaluation of urine culture and urinalysis three to five days after initiating therapy allows for verification of antibiotic effectiveness before the development of irreversible organ damage or systemic spread of disease. The same strategy should be considered when prescribing antibiotics with a high risk of toxicity.

My Cat Suddenly Began Going To The Litterbox Very Frequently A Sample Of Urine Revealed A Bladder Infection How Did This Happen
While urinary tract disorders are fairly common in cats, urinary tract infections are fairly uncommon. Cats with UTIs try to urinate very frequently, they may pass only small amounts of urine, they may strain to urinate, they may cry out or whine when urinating, and there may be blood visible in their urine. Urinating outside of the litterbox is also a red flag that something is wrong in the bladder. Finally, frequent licking around the rear end may signal that a UTI is present.
Generally, a UTI occurs when bacteria travel up the urethra and into the bladder. Urine in the bladder is supposed to be sterile, but once bacteria find their way to the bladder, the bacteria can grow and reproduce, causing the UTI. Some cats will develop bladder stones, with or without a UTI, and this opens the door for additional health issues.
Why Should I Take The Full Dose
Antibiotics work well against UTIs. You might start to feel better after being on the medicine for just a few days.
But even so, keep taking your medicine. If you stop your antibiotics too soon, you wonât kill all the bacteria in your urinary tract.
These germs can become resistant to antibiotics. That means the meds will no longer kill these bugs in the future. So if you get another UTI, the medication you take might not treat it. Take the full course of your medicine to make sure all the bacteria are dead.

Diagnosis And Prescription Of Antibiotics For Cats
The antibiotics that the veterinarian prescribes for your cats urinary tract infection have to target the specific bacteria causing the infection. Veterinarians perform a urinalysis to identify the cause of the infection. Depending on the result, he will prescribe the most appropriate antibiotic. When prescribing antibiotics, your veterinarian will take into consideration the toxicity and the incidence of side effects. Most common antibiotics for UTI in cats are:
Diagnostic Tests To Rule Out Cat Uti
A urinalysis must be done as the first step for ruling out whether your cat has a bacterial infection thats causing the urinary symptoms like commonly peeing outside the litter box.
You should never just put your cat on an antibiotic since stress cystitis is the number one reason for cat urinary problems.
Other diagnostic tests your veterinarian may recommend include bladder ultrasound to rule out sludge and bladder stones, an abdominal radiograph to rule out bladder and kidney stones, and a urine culture.
A urine culture is very helpful to make sure the right antibiotics are used if your cat has bacteria in its urine on the urinalysis.; Antibiotic resistance is, unfortunately, becoming a bigger issue and many commonly used antibiotics are not working as well.
Doing this test will speed up treatment and help your cat feel better, usually meaning less vet visits and expenses in the long term.

Bacterial Urinary Tract Infections : Symptoms Diagnosis And Treatment
A urinary tract infection usually refers to a bacterial infection of any or all parts of the urinary tract, but it most commonly involves the urinary bladder .
UTIs are common in dogs, especially females, but are uncommon in cats less than 10 years of age. However, cats older than 10 years of age have a higher risk for a UTI, which is often associated with other diseases .
Two things must occur for presentation of a bacterial UTI:
1.;There must be a break, either temporary or permanent, in the animals defenses.2.;Bacteria must migrate into the urinary tract, catch hold and multiply.
Diagnosing Urinary Tract Infection In Cats
When diagnosing a UTI, your veterinarian will begin by taking a complete medical history. The vet may ask about changes in your cats water consumption, frequency of urination, amount of urination, how the urine looks, and any behavioral changes. Your vet will also perform a physical examination to assess the bladder and kidneys, as well as the genitalia and sometimes the rectum. If there is trouble with urination, a neurological exam may be conducted.
Your cats urine and blood will also be tested. Urinalysis is one of the most important and useful tests for diagnosing a UTI. It will look for the presence of certain chemicals or substances in the urine, like sugar, ketones, bilirubin, blood, and protein. A urinalysis is best conducted on a fresh urine sample to prevent inaccurate results.
Based on the findings, additional testing may need to be conducted. In particular, a urine culture may be performed to confirm the presence of an infection and to determine what type of bacteria are involved. Since it often takes 3 to 5 days to obtain final culture results, your veterinarian will likely start your cat on broad-spectrum antibiotics in the interim. The typical duration of antibiotic therapy is 7 to 14 days.

Antechs Rapid Urine Culture
According to Michelle Frye, DVM, SM, owner of Echo Lane Animal Clinic, in Houston, Texas, veterinarians must gather a detailed history report from pet owners. She recommends asking questions about the duration, the frequency and location of the accidents, and urine color.
If its a suspected UTI, the next step begins with Antechs FIRSTract test, the first reference laboratory automated assay for quick urine culture, delivering accurate and reliable results within hours.11
FIRSTract utilizes 500 µL of urine inoculated into a proprietary culture broth optimized for aerobic bacterial pathogen growth and incubated in a controlled and fully automated setting. During the incubation process, the samples are temperature-controlled and continuously mixed, minimizing sedimentation, flotation, and growth abnormalities typical of several microorganisms. Interference from erythrocytes, leukocytes, and dead cells is minimized by obtaining an initial baseline reading of turbidity. Light scatter is measured and assessed from the sample turbidity of the inoculated broth. Measurements are taken every 5 minutes and continually monitored for an exponential increase in turbidity that is consistent with the presence of any viable bacteria replicating in the patient urine sample.
