Why does my cat have a puffy chin, drooling, and sores on tongue/nose?

This looks like a condition called eosinophilic granuloma, it's an autoimmune disease related to various allergies as well, you need to bring him to the vet ASAP, the treatment for this condition is usually done with steroids and hypoallergenic food.

The lesions on Chubbs' chin and mouth could be feline acne, viral in origin, among others. Make sure that Chubbs is eating from stainless steel or glass bowls rather than plastic or ceramic, as these materials are more porous and can harbor bacteria, leading to irritation of the chin and feline acne. You can also use dilute antiseptic solution (such as betadine or chlorhexidine) to clean his chin 1-2 times per day, but take care to rinse and dry the areas thoroughly. If he continues to scratch, you can put an e-collar (cone) on him. However, if the lesions persist or worsen, Chubbs may need to go to his vet for further evaluation and medication, such as antibiotics and/or steroids. I hope that he's on the mend soon!

This condition is called Eosinophilic Granuloma Complex , also known as "rodent ulcer", The exact cause of feline eosinophilic granuloma complex is unknown. Some research studies suggest that a form of allergic response (hypersensitivity reaction) may be involved in the majority of cases. This is more likely in cases that are recurrent. Other studies suggest that the condition may at least be partially genetic or inheritable. Flea and insect control is very important in the treatment of feline eosinophilic complex. This is due to the suspected hypersensitivity reaction cause of the condition. Insect bites can trigger an exaggerated immune response in affected cats, causing or worsening clinical signs. Some cats respond to elimination or hypoallergenic diets, suggesting an underlying food allergy as the cause. Most cats diagnosed with feline eosinophilic granuloma complex benefit from a hypoallergenic food trial. Corticosteroids are the most common treatment to control the symptoms of eosinophilic granuloma complex. you will need to visit your vet to get this treatment.

This is probably a condition called eosinophilic granuloma, it's an autoimmune/allergic reaction, very common in cats. the treatment is usually with steroids, you will need to take Romeo to the vet for that. it's not contagious.

Cats can develop something called gingivostomatitis as well as feline oral resoptive lesions. These are both very painful and require antibiotics and sometimes steroids as well as dental procedures to correct. Also if there's any possibility she chewed something like electric cord or plant that can calls the signs as well. I recommend Dusk be checked out by a veterinarian as soon as possible. This is to prevent her from becoming dehydrated and malnourished from not eating. Do not give her any human medications as they are very toxic to cats and I'll make the situation worse.

Ouch, poor Binx! I agree that it could be infected, and he's probably drooling more from the sore on the corner of his mouth. He could have injured himself causing the sore. I would have him seen by a vet for this sore because if it is infected, he will need antibiotics to treat it. I would take him into the vet today.

Thank you for submitting your question regarding Sam. Yes, I recommend that he sees his veterinarian. The wound could be the result of a condition known as an indolent ulcer. If so, it will require treatment before it progresses any more. This condition is typically the result of an allergy to something in the environment, diet or even fleas. I hope this information helps!
