Awww... the vids are too adorable!!
Does your cat get along with your rabbits? I had a dwarf rabbit named Snickers one time that was litter box trained and basically had run of the living room and kitchen (with much rabbit proofing of course!!). She used to run up to one of the cats (usually the one that was twice her size) and basically pounce on her then dart in the other direction, which would then start a game of bunny/kitty tag. Then when they all tired themselves out, Snickers used to curl up with the cats and go to sleep. I have pics somewhere..will have to scan them into the computer sometime.
