My skinny, inactive kitten has black mouth substance. What to do?

Since the mother cat is refusing to nurse or care for this kitten Brownie is probably suffering from a failure to thrive. If you are not doing so already, I would recommend supplementing her with a bottle of some kitten milk replacer. She’s probably not getting the nutrition she needs if the mother is not caring for her. She may also have a respiratory infection and/or intestinal parasites that need to be addressed. I would try bottle feeding her every 2 to 3 hours for a 24 hour period. If there is no improvement after this then I would recommend taking the small kitten into the vet to be examined. I hope this helps. Thanks for using Petco Pet Education Center, formerly Petcoach. Best of luck.

This "black gunk" could be saliva that is getting dirty (cats often salivate a lot when nauseous), if the vomit itself is black then it means he's vomiting up digested blood, or it could be discharge from a skin infection. Since this is such a wide range of possibilities that would all be handled very differently, I'd recommend a vet visit for evaluation for this one. Good luck!

Those lesions could be related to ringworm (which humans can get) or mites. I recommend to have Bora visit her veterinarian for diagnostics and treatment. I hope this is helpful and please feel free to post any additional questions.

I am sorry to hear about your kitten. It looks like she could have an infection of the skin around her mouth, such as perioral dermatitis. This requires treatment wtih antibiotics. I would recommend having her examined by a veterinarian who can then prescribe medication to treat this condition.

Based upon the lack of response to treatment, it’s likely Kuskus has an internal disease like renal disease or hyperthyroidism but many many conditions will cause these clinical signs. Dental disease is also possible. At this point, he needs to be examined by the veterinarian and needs bloodwork to check his organ enzyme levels. Have him examined today before he gets worse. I hope this helps and please feel free to post any additional questions.

Hello. I am so sorry that poor Blackie is not feeling well. I am not sure what a mood booster is, we have nothing like this in the US, but your veterinarians should be doing blood work to check her feline leukemia & feline AIDS status, a complete blood count with blood smear to look for red cell parasites, serum chemistry & urinalysis. We do have appetite stimulants that may help, but Blackie should possibly be on antibiotics & a syringable food to at least get some calories into her. Check back with your vet to see what they recommend as the next step to help Blackie feel better. Thanks for using Petco Pet Education Center, formerly Petcoach.

Poor Princess. I'm not sure how old she is, but this black thing in her mouth could be something serious like cancer, and if it is getting bigger, that would make it hard for her to eat, which is causing her to lose weight. This is a medical emergency, and she has to see a vet now. You need to take her into an ER vet immediately.
