My cat's head is swollen, breathing hard, and won't eat. What's wrong?

It is extremely concerning that Peanut has a swollen face and ragged breathing, and I would be very concerned she could be experiencing an allergic reaction. It could also be that Peanut was attacked by another cat if she's allowed outdoors, and that could be causing the swollen face, breathing difficulties, and vomiting. When a cat is having problems breathing, it is a medical emergency and she has to be seen by a vet now. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website.

Oh my. This sounds like your poor Thor may have been bitten by something in the face and is in need of immediate medical attention. Most cats will still eat even when they are a little bit ill, so when a cat decides not to eat we know they are in trouble. I would highly recommend taking Thor into your local ER vet right away for care. If you can't make it in tonight then it's best to have him seen in the morning for testing and treatment depending on what the underlying cause is. Best of luck with your fur baby I hope he feels better soon.

Terry needs to be examined by the veterinarian today. The most common reasons for a swelling like this are tooth root abscesses, skin abscess or an allergic reaction (which is the least common). Abscesses can be very serious and cause sepsis if not treated so I recommend to have him examined today for the correct diagnosis and treatment. I hope this helps and please feel free to post any additional questions.

Hello, it looks like an abscess, probably a tooth abscess, it's an emergency as he is not eating, take him to the emergency vet as soon as you can today, the abscess will need to be drained under anesthesia first, then a course of antibiotics will be given.

This may be the start of an upper respiratory disease. They usually do have a fever and swollen lymph nodes (possibly causing the face to swell) early in the infection, which will make them feel bad. They also tend to avoid eating and drinking early in the infection. It appears that both sides of Blue's face are swollen, but if it happens that only one side is swollen, then this can indicate a local infection/abscess. This can happen with bite wounds, other puncture wounds, or dental disease. I wouldn't be too concerned about this being an emergency, but it's best if you can get Blue to a vet within the next day or two. While these infections are often mild, they can become complicated, which will make things much worse. The vet would be able to narrow-down the cause of this and prescribe the necessary treatment to make him feel better and keep the infection from getting worse. I hope this helps and Blue feels better soon.

You need to take Naila into a vet immediately, this is a medical emergency. I would be very concerned she has head trauma, which would cause the head tilt, blood from the nose, and the anisocoria (one pupil more dilated than the other). When anisocoria comes on suddenly, this is a medical emergency. Please take her into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. I hope this helps!

Oh no, poor Ollie. The swollen face could be from an accident, getting into something toxic, a fight, or an allergic reaction. I cannot say what is causing his symptoms without seeing him in person, but I can say for sure he needs to see a vet now to diagnose what is causing it. Please take him into an ER vet clinic; if there isn't one in your area, there will be a vet on call for emergencies. The information to reach that vet is found on a clinic's answering machine or website. Best of luck.
