I have a thing called a cat tickler - its tinsel and feathers on the end of a bendy pole about a metre long. That gets hidden here because bastet promptly sits there and licks it to death before pulling it appart! Or she drags it around the house!

Her mousies get a work out - most of them are balding now from hunts! She also likes catnip fish-on-a-string. Its fun fishing for her. That gets hidden as well or else she chews the string to death!
