Why are my cats sick, vomiting, and not eating after a fight?

Thank you for submitting your question regarding Albert. I recommend that he sees a veterinarian today. Cat fight wounds are very common after being outside. The veterinarian will examine him and look for any wounds. If there are none, laboratory work may be discussed. He may also be given fluids if he is dehydrated and pain medications to help him feel better. Do not give any over-the-counter pain medications as these can be toxic to cats. I hope this information helps!

Poor cats. Yes cats can catch bugs and get ill just like people can. And since both were sick simultaneously, it has to be something they both got into and ingested or were exposed to. It is very odd that nothing has changed in their environment, so finding out the culprit is going to be tough. You also may want t check with the company that made the filter you just changed just to make sure no recalls exist. Also I would consider just changing the filter altogether just to cover every possibility here. Also make sure that there also isn’t any chance of them getting into medications in the home as well. Regardless of that, they should be seen by your vet if they are still not eating and unwell. That is a long time to go without a good appetite, especially for a cat, and at the very least the vet can give them anti-nausea medicine, antibiotics (if indicated), and fluids to treat for any undelrying dehydration. I hope your cats feels better soon. Best wishes and take care.

He may have not escaped uninjured. It is possible he was bitten and is developing and infection or abscess. Cat bites can be difficult to spot. Ideally, he should be physically examined by your veterinarian. He may need antibiotics and pain medications.

Poor baby. It sounds to me like he needs additional medical attention. His pain control may not be adequate for his injuries, or he could be developing an infection. I would recommend taking him to an emergency vet clinic tonight to be assessed and his treatment adjusted.

Cats will often go off their food and be more lethargic when they are coming down with an illness. This is usually due to an upper respiratory infection (aka cat flu) or an infection of the stomach or intestines. While she may not be having nose/eye discharge, or diarrhea right now, you may see this in a day or two. Their are a couple of other diseases that I worry about with a fighting cat, because they can cause them to feel bad like this and be spread through biting. FIV and FeLV are two viral diseases that can depress the immune system and possibly lead to long-term infections. These can be easily tested for by a vet. If she is eating a little, then make sure there is plenty of water mixed in the food, because I worry most about dehydration. Sometimes warming up the food will entice them to eat it, so try that along with trying different, tasty foods. The best thing to do for Alba is to take her to the vet. She may be running a fever and could already be dehydrated. They also may see something else that indicates what her specific aliment is. It doesn't seem like an emergency right now, but it would be best to get her to the vet within a day or two. I hope that helps and Alba gets better soon.

No, it's normal for cats not to eat, and it could be they have gotten sick from being out in the cold. They could have developed a respiratory infection, making them congested. When cats are congested, they can't smell their food, and that will keep them from eating. The problem with cats not eating is that if they go longer than three days without eating, they are prone to developing a fatty liver. I would take all three cats into the vet tomorrow for an exam. If they do have a respiratory infection, they may need antibiotics to treat it. You can try to tempt them to eat, in the meantime, by gently warming up really smelly wet food, such as sardine or fish based. You can also starting them on an L-lysine supplement - this is an amino acid that has been shown to help the immune system fight off respiratory infections more effectively. Enisyl and Viralys are both good brands, and can be purchased over the counter without a prescription - just follow the dosing instructions on the label based on your cat's weight.

When a cat gets into a fight, they often get bit, and bacteria from the other cat's mouth can cause an abscess at the bite site. Those are very painful to cats, and would cause them to be nauseous and lose their appetite. I would take Shammo into a vet today for an exam.
