Ooh . . .
He was rolling in the catnip plant in front of his nose in the first pic. (it had self seeded)
He is lovely - I have known him since a kitten. The bunnies on the other hand do not like him!
I'm sure your rabbits don't like him! Mine are fine with my 'family cats' but are very uneasy if any others comes to the garden. He looks like a Bengal or Bengal-cross?
