Zippers are well-known to all kittens as things they should groom off of the hapless people holding them. The zipper pulls should be removed and the tracks crunched. This also works as a toothbrush for the kitten. They continue to do well, and I may have stopped using the bottle for the littles.
Only one viewer today, so I’ll add on. Their vet visit was again handled with full precautions. They only tested Anza, who tested strongly positive last week. He got a weakly positive today. They all are behaving and growing as if they are perfectly healthy.
