My cat has a fever and hasn't eaten for days. Can I give Amoxicillin?

Hello. Thank you for reaching out to Pet Coach. I am not familar with the antibiotic that you specifically have mentioned. However, in the US we do use something that sounds similar, called Clavamox. Either way, all antibiotics should be given with food if at all possible to avoid upset stomach. Many cats have a reduced appetite when they have a fever, so it is not surprising that Haro Kitaru is not eating on her own. I am very sorry that she is feeling ill and has a fever. If you are able to give her a small amount of chicken or turkey baby food before administering the antibiotic that would be best. This will reduce the chance of causing an upset stomach. Or you can offer her canned tuna or chicken as well. Best of luck with your kitty. I hope she is feeling better soon.

I strongly recommend getting your cat seen by your vet as soon as possible. Cats can sometimes get fevers with no known origin and it makes them not want to eat. A cat cannot go more than a couple days without eating before they develop liver damage. Your cat may need fluids and supportive care in order to lower his temperature back to normal and support him until his appetite returns.

Hi, has he had any blood tests ? If so, are these all fine ? If no suspect of pancreatitis or liver disease he could have some Hill’s recovery food, slightly warmed up and offer small amounts little and often. You could also offer a small amount of tuna in water or sardines or white fish. Try to encourage him to eat spontaneously, now that he has received some medications, his temperature might drop and he might feel more inclined to eat. If by this afternoon he stilll has not eaten, I would recommend to try with syringe feeding some recovery diluted with water. If he should not eat, I would still recommend that he is on a drip, at low fluid rate and he receives antibiotics intravenously. Hope it helps.

It's very concerning that your cat is refusing to eat. When cats don't eat, they develop a fatty liver that is fatal without treatment. It could be he's really congested and can't smell his food, leading him to not eat. Try gently warming really smelly wet food such as sardine or fish based to see if he will eat. If he does not eat that, take him back into the vet today. Best of luck.

He should be examined by a vet before giving any medication, especially if he is not eating. He may have an infection but a vet should look at him first to decide if Amoxicillin is the best antibiotic to use. He may also need some fluids to prevent dehydration. Please call your vet and have him examined. Your vet can check a urine sample to look for an infection or other diseases that can cause blood in the urine. Hope he feels better soon!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Chimpu! Sadly I can't give you a prognosis with out a diagnosis and we can't do that over the internet. Chimpu needs to see a Vet for an exam, blood work and X-rays. Cats shouldn't go longer than 2 days with out eating as that can cause a secondary serious liver problem (fatty liver syndrome). Causes of a fever in cats are: viral or bacterial infections, feline infectious peritonitis, feline leukemia, pancreatitis, blockage from a foreign body and cancer. I do think this is serious since it has been 4 days. He should be hospitalized if possible until we find out the cause of his fever. I am not in full agreement that he won't survive, but I am worried he won't with out intervention. I wish you and Chimpu the best!

If Jamie has a fever he should be seen by a vet ASAP and not be told to wait. I would try to find another veterinarian that will see him ASAP especially if he is no longer eating and has signs of a bacterial infection. Not eating or drinking can severely dehydrate a cat as well as lead to liver problems, so seeking veterinary care in person immediately is needed.
