Its a mystery?

Cassie Cat's favorite object is ... me ... her food server, dish washer, litter box cleaner, masseuse, and whatever else I am to her!

Mango's favorite toy is a little fluff ball with a pipe cleaner wrapped around it that he got as a two-month old kitten. Almost eight years later, he still plays with that toy.

Milly is obsessed with the plastic rings that you pull off the milk jugs.
She will carry them around in her mouth, toss them around with her paws and meow at someone to play with her. She will fetch them if you throw them down the stairs and will sit up and beg for them loudly if you hold one up over her head. Sometimes she will snatch it up in her mouth on her way out of a room just to keep it close to her.
Izzy love pink furry mice and her favorite ornaments to bat around are purple and blue, we don't have any pink ornaments for her but I am sure those would be her first color choice if we did.

I keep reading about how cats love the milk rings. So I started saving them and would throw them on the floor for the cats.

All of them looked at me like "are you crazy? you really expect me to play with that?"

Pearl is obsessed with straws even though I don't let her play with them very often. She also loves most of her tiny furry mice but is constantly losing them.

Sky came with a brown catnip mouse and he still has it. He used to sleep with it every night and will still play with it sometimes. It's getting very worn out.
