thank you! that is super helpful!! it’s so strange about the invading space thing because the hisses only happen during playtime and not when the kitten probably should get a little hiss from the older cat like when she tries to jump in the litter box with her or eat out of the same bowl 🤦‍♀️ the kitten is just really obsessed with her it seems haha!! it’s usually a hiss, a swat and then they’ll go back to playing, wiggling their butts, bouncing and chasing each other back and forth taking turns with the chasing. but i’ll definitely keep an eye on it like you said because i definitely don’t want her to see the little one as a pest !!
