Two weeks ago our old female cat (15 years old) started with a slight snoring and dificulties for swallowing, sometimes even choking while eating. We consulted a vet, who found a red sore throat and diagnosed pharyngitis, and treated it with injectable antibiotics and anti-inflammatories.
The first days she became better, but then at the third, she refused to
eat or drink and slept the whole day. The vet suspended the drugs suspecting that they were too much for an old cat and that she was intoxicated. She spent two days sleeping refusing to eat or drink but to our surprise urinating daily; and then two days ago she started to walk around, asking for food, scratching the mat. But she still can't eat or drink and she is dangerously thin now, her snoring continues and it has a thick saliva.
Yesterday the vet found two big pale blisters under her tongue 1 centimeter wide, that weren't there three days ago when she checked her mouth. The vet started with antivirals, but she told us that she has never seen something like that because it does not look like calcivirus or viral rhinotracheitis, the teeths and gums are okay, she doesn't have fever, nor oral or nasal secretions, and it's doesn't look like a tumor.

I know we're running out of options, and that it is an old cat, but perhaps some of you have seen something like that and can help.

Thanks in advance.

PD: english is not my first language, so sorry if any mistakes.

I don't know what it could be, but I would recommend syringe feeding her to give you and the vet more time to figure this out. She needs nourishment or you will be dealing with fatty liver disease on top of whatever is causing the blisters.

I am so sorry that your cat is sick. She really needs food and water in order to give her a chance to recover.

Thanks, I forgot to mention that we're currently feeding her with a syringe.

Sounds like mouth ulcers.  Did the vet not give you some pain meds (not Metacam) to give your kitty on a daily basis to help with the pain?  If not, get some.

Hi oldcat321 and welcome to TCS !

I have a HUGE concern about the drugs your cat was given.....please read through the following very carefully:

IF the injectible antibiotic was CONVENIA......

AND

IF the anti-inflammatory was meloxicam - METACAM ...or other drug ending in com/cam

YOU HAVE TO TAKE IMMEDIATE ACTION and have your cat put on intravenous fluids for several days, perhaps 5-6.

These two drugs MUST not be taken together/simultaneously........each has specific warnings contraindicating their concurrent use.

Not long ago, we had another case like this.......you can read the story here: http://www.thecatsite.com/t/258906/whats-wrong-with-my-cat

The outcome of that story is recorded in the first post here (#26) : http://www.thecatsite.com/t/244226/convenia-side-effects#post_3382919

AND, obviously, she needs CONTINUED ASSIST-FEEDING!

Please post back with the 2 drug names...........and, where (country) are you located?

Thanks for your concern. I'm from Uruguay, the anti-inflammatory used was dexamethasone, I can't remember the antibiotic name but I'm sure it wasn't convenia/cefovecin (first time I hear it) it was something with -oxi. I also remember that the vet explained us that some antibiotics/anti-inflammatories can't go together.
