Hi
I don’t have much experience with cat and rabbit relationships, my bunny’s have met my mom’s cat and they were just scared and hid and they have also met my sister kitten which they both seemed to really enjoy and even tried to play, probably cause it was so small and not very threatening.
If I were to guess it looks as though maybe clover isn’t to happy with the cats presence, in the video it looks like he tried to lunge/chase the cat when the kitty goes near his litter tray and food, so perhaps he feels like the cat is challenging his territory so wants to act out?
It can be hard to tell from a vid if this is playing or chasing but I’d say maybe chasing as there’s no binkying as it looks like he’s trying to nip him
Maybe try introducing them in a different room that doesn’t belong to clover?
Hopefully someone with a bit more experience with rabbit and cat relationships can give some better advice but thats my guess.
They are both very cute!
