Am I the only one that finds this inappropriate?

Has anyone watched some of these YouTube channels for kids with kids on it maybe reviewing the toy or something or playing with animals and then they just say something about pussy? My son was watching a YouTube video and the little girls were playing with their cats and said what some good pussies,(No cat at the end) I was literally in shock and took the tablet away from him so now I monitor a lot closer. I don’t want him going around cats using that word I don’t think that’s ok for a child to say! (I hate this word so much, I don’t even like typing it) Am I crazy or is this inappropriate??
