My 3 are all entirely different and therefore love different games based on their special talents:
Eldest is agile and therefore loves long distance running about and jumping high to catch a toy in her mouth. She is all about distance and speed like a cheetah.
Middle cat I think was a r*nt (hate that word) and doesn't run or jump high, but she is a gymnast and likes turning things into forts to defend with her paws or she likes performing acrobatics on the bannisters, her rl specialisms would be the beam and double bar. She is also magnetised to boxes and baskets.
Tom kitten (7 mths) loves to play fetch. He also likes tug of war and doing back flips. he is a dab hand at ping pong football. He acts like a butch alpha male but squeaks like a girl and loves hugs. He is hard to keep entertained.
I have cardboxes with holes cut out, big toys, little toys, toys of different texture, cat activity thing, scratching posts galore, toys on a string, catnip toys, a scrunchy tunnel, cat beds etc but I struggle to wear him out.
Any suggestions?
