I’m just curious what people think about this. I don’t see any reason to worry about anything and this is probably a good thing. My wife and I have 2 cats. One is a 2 year-old boy and the other is a 1 year-old girl. They aren’t biologically related at all. We had the boy for over a year before getting the girl. At first the boy hated her but now there are times (usually at night) when they will spend a long time playing. I see her walk over to him a couple times a day to get cleaned. He does most of the cleaning, but she’ll clean him a little. Why does she walk over to him to get cleaned? Thanks.
