My cat has a fever and won't eat. Can I give antibiotics without food?

Updated On September 23rd, 2025

Hi. I took my cat to the vet. She has been vomitting. Vet said she has fever. She gave us antibiotics. It's coamoxiclav. I forgot to ask if cat should eat first before the intake. Im home but could not reach the doctor's number given to me. My kitty won't eat. May I still administer the med?

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'm sorry Haro Kitaru has been so ill lately! Yes you can give it to her without food, but keep in mind that some animals do vomit after receiving this medication due to stomach irritation. I would see if she will eat some boiled white meat chicken (no bones) before giving her this medication.
