My cat has a fever after new kitten. Did she catch something from it?

You can try warming the food or mixing in a teaspoon of baby food into it. This could stimulate her appetite. You can also take her temperature to check for fever. Use a rectal thermometer and sterile lube. Normal temp is between 37 C and 39 C (100 F- 102.5 F). Anything above that is considered a fever and should be addressed by your veterinarian.

If the fever persists longer than 12hours, she becomes weak or refuses water for longer than 4hours you should return to your vet. Do not give any human or other medications to such a young kitten but keep her in a cool, well ventilated area with easy access to fresh water and soft food. Most cases resolve uneventfully without additional treatment

That is a nirnak temperature for cats! It can go up to 102 without being considered a fever. If he is eating and drinking well then I would monitor him for any changes. He may have over done it and just need a rest. If he is not back to normal after 24 hours then I would get him checked.

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.

I typically don't recommend treating the fever specifically as fevers are a normal reaction to fight infection in the body. Like a cold in people, upper respiratory infections in cats can take several days to resolve. As long as she's eating and drinking normally, that is a good sign. If she stops eating and drinking or gets very congested and is breathing through her mouth, I would recommend taking her back to the vet. Occasionally upper respiratory infections get so severe that cats need to be hospitalized for IV fluids and syringe feeding until the symptoms improve.

Fevers in cats are really frustrating. They can have many causes, and sometimes we can’t find any cause at all (Fever of Unknown Origin - FUO). Sometimes IV fluids can help with the fever, and sometimes it will go away in a few days with or without treatment. As long as he is comfortable and eating, I wouldn’t be so concerned. It sounds like your vet has a good plan for treatment.

Poor Lucy. It is always sad when our babies are sick and not feeling well. I have attached a handout below that discusses upper respiratory infections in kittens. https://www.veterinarypartner.com/Content.plx?P=A&S=0&C=0&A=613 These infections can be viral or bacterial. Sometimes an infection will start as a viral infection then develop a secondary bacterial infection. Cats normally are warmer than humans and have a normal body temperature of 100-102.5 degrees. If Lucy has a fever of over 103, I would recommend having her evaluated by a veterinarian if you have not already. If her infection is viral, she may just need some time and supportive care to make her feel better. I like taking kittens into a humid bathroom for 5-10 minutes (after you have showered) to help loosen their congestion. And make sure she keeps eating. Cats need to be able to smell their food, so you may need to feed her some smelly canned food to keep her eating. If Lucy develops yellow or green nasal discharge, is very lethargic or will not eat, I would recommend having her evaluated by your veterinarian. Good luck! I hope that was helpful and that Lucy feels better soon. Thanks for using PetCoach.
