Kuro snivels green snot often, I asked about it. It's because of her mother (she was a stray cat), she has a chronic sinus problem, the vet said. It could be better as she grows up, I hope so. She had a clod badly when she was found, it might be the cause.
Kuro is a cat, so she licks, not sniffs it.
Then, they passed a midnight athletic festival and just sleep. Looks languid. Kittens got fever because of preventive injection often, there is nothing worried about people said on the web.
May is getting better till this night, but Kuro is still sleeping, don't play.Both of them ate some food (less than usual) and peed, so I think they are OK. Ｗａｉｔｅ and see...
