My young kitten's private area is inflamed. Is dog licking dangerous?

Hi there. The only possible problem would be if your kitten has any intestinal parasites-then your dog could also get them if ingesting the feces. It is not uncommon for females of different species to show "mothering" instincts toward young. Hope this helps!

The kitten is likely still missing its mommy. Kittens normally stay with their mother until 10 to 12 weeks of age, but, unfortunately, humans take them away long before that. So your male's penis is the closest thing to a nipple to get comfort from (suckling is not just for milk but also for comfort).

That area is very infected and inflamed. There is not much you can do at home except give him a bath and keep it clean and dry. Keep the other kittens away so it can be spread or they can't make it worse A vet will have to examine how deeps those go and some antibiotics.

I would be concerned this may be a sign of inflammation and part of the FLUTD (feline lower urinary tract disease complex). It is important to act quickly here as some cats can suffer extremely painful and severe blockages if untreated. Pain relief, antiinflammatories and sometimes catheters re required to relieve if very severe and he may need antibiotics if there is any evidence of infection. Dietary management long term can help to prevent recurrence depending on his test results

Unfortunately the best thing to do would be to take Willy to the vet to make sure there isn't an infection or irritation causing him to want to lick and chew at his genitals. You can use an Elizabethan (cone) collar to try and stop him and reduce irritation, but if the problem continues along with his failure to grow, an exam is needed.

I agree with you. The top of the anus does look swollen. I do not know what from. He needs an exam in person from your vet. In the meantime you can just apply a thin layer of Neosporin to the affected area to hopefully soothe him.

Because Sombra hasn't had wet food before, it could be this causing her red and swollen anus. But it could also be due to something else like intestinal worms. Based on the picture, I think having her seen by a vet before you leave is the best idea. You don't want it to get worse while you are gone, so having her seen before you leave will give you peace of mind on your trip. Call the vet today to make an appointment. Best of luck, I hope this helps.
