I guess she was in her first heat? Thats really odd to me I never seen that happen on anyother kitten before. It is going away on its own. Almost all gone and one week ago. But its still a little bit there.
Went to the vet, she said she didnt know what was going on and to leave it alone for 2 weeks unless my kitten had stopped eating, hiding or got diareaha. Kitten acts normal no fever regular activities.
I have the same exact problem. My kitten is 4 months old. I took her to a vet clinic for rabies they ran out of the other shots when I was there. Now 6 days later lumps on all her nipple areas. Just happened real quick, size of dimes otherwise normal. Feeding her kitten chow mix with IAMS...
