My name is ***** ***** I am an experienced small animal veterinary surgeon, I will be very pleased to work with you today and will try my best to answer your question to your satisfaction.
While the symptoms you describe would not allow me or any other vet to pin this down to any one particular disease via the internet I would say from the fact that she has no interest in food and water and is lethargic that it is possible that she is running a temperature and so may be in the grip of some kind of infection.
I am worried about her she is a very fussy eater but will normally eat well. It is not like her. Could this be a return of her liver enzyme issue or could it be cardiac. She is breathing in a shallow way
It could be that she is running a temperature or it could be the return of her previous disease, the breathing is a cause for concern as well
The problem you have is differentiating between something minor such as an infection or a recurring liver problem at home
I normally like to suggest home remedies if I can do this safely but in your case I think it is not worth the risk as it could well be that antibiotics would be what is needed if your cat is indeed running a temperature, but you should be aware that other diagnosis are also possible such as liver issues ...
All you can really hope to do here is to keep her comfortable and reassured, try and get fluids into her orally if possible, and if symptoms continue have your vet check her over
She is quite bright but I am worried. I shall watch her carefully tonight and take her to my vet first thing in the morning. I have three other Persians I am supposed to be taking one of my other Persians to an old folks home for a visit I think I will cancel in case of infections?
Thank you for your advice
If your other Persian is clinically normal at present then I would not worry, there would be little risk of cat diseases spreading to humans. Cat diseases are usually very specific to cats and do not affect people.
Thanks. I will take her first thing Good night
Glad to have advised you, I am just sorry I cannot safely give you any more specific advice via the internet.
Good night, I will be about for at least the next four or five hours so please do not hesitate to get back to me if things change ...
I will do, I have had cats all my life and just adore Roxie. If I get any more worried the Glasgow vet school is fairly nearby and has a 24 hour emergency room, I hope she will be ok until the morning.
