Too much Baytril for cat?

Hi all, My 15 year old, 8-lb cat has had a recurring UTI for the past 8 weeks (fun for both of us.) I've taken her in to 2 different vets the 3 times I've seen her straining/peeing on anything other than litter and have been given scrips for Clavamox or Amoxidrops (along w/sub-cutaneous fluids).
The last time I went in to a new vet (he came recommended), he prescribed 22.7mg Baytril, 1x daily. I googled Baytril and many sites warn that cats should not be given more than 5mg daily. Now poor kitty has diarrhea.
So smart folks, should l heed the vet websites I've found by Googling "Baytril" or should I trust this new vet? Please be kind...Thanks!

(btw, she has been checked for tumors/stones and doesn't have any, she's been diagnosed in kidney failure, but the new vet said,tho her left kidney is shrinking, blood work doesn't show kidneys failing) Thanks again!

Hi, First of all I like to say that not all websites can be trusted.
Yes , baytril can cause toxicity in cats - signs like vomitting, inappetance and diarrhoea can occcr. In worst cases, it can cause blindness. However this is if the dose rate is up to 15mg/kg.
Note that you have not actually said how heavy your cat is. The usuual baytril dose is 5MG PER KG. NOT 5MG DAILY.

It is good that your cat has been checked for stones and tumour. But have they checked it for the bladder or kidney.
If necessary, get your vet to either do a radiology examination - x ays or ultrasound is good. Ultrasound is preferred as they can measure how big the kidney is and how well defined the medullary is ( that is the inside of the kidney)
The vet is right in saying that sometimes although the blood works seem fine, the kidney is stil failing This is because if part of the kidney is dead, it would not release any enzymes into the blood stream but the part of the kideny that is inflammed will be releasing lots of the enzyme into the blood stream. So it kind of balances everything out.
The best thing is to go back to your vets and seek a better undersatnding of your cat's condition.
One last note, if the kidneys are fialing, it is probably not producing as much urine. This can encourage bacterial growth and could account for the uti.
Hope it helps. Please talk to your vet about your fears. They are there to help you and your cat.
I am assuming the baytril is in liquid form. If this is the case, the dosage is actually 22.7mg/ml. either way, you should absolutely trust your vet, and never trust a website. If you have questions, they should be directed towards the veterinary office.
I agree with Gigo, I think you may have misread the website or it was wrong. Baytril is typically 5mg/kg (for example a 10lb cat is approx 5kg, so it would require 25mg)
Definitely trust your vet.

Have they done a culture and sensitivity on the urine? It would tell you what type of bacteria is in the urine and what antibiotics its susceptible to.
