OK. That's just weird. My lil cat believes she DOES have opposable thumbs ! She can pick up a piece of popcorn from a bowl or unwrap a Hershey's Kiss. If I have kisses she HEARS them and comes running to steal them, opens them up ~ didn't even know at first until we found wrappers and chocolates everywhere. She also HAS to do whatever I am doing, and copies every move so I am not too surprised your Kitty is cleaning closets too ! Try this one: get into a stare contest and wink. Yes, Kitty will wink back. It took awhile for her to get it right, but it was cute watching her try. Now she is very proud of it and will initiate a stare- wink. She has another "code" If I lick my lips, she licks hers , then comes to me. She is my obedient child, and comes when called, but if she's feeling stubborn, waits for a whistle ~~ not a simple one, she won't come until she hears Gershwin's Rhapsody in Blue, The Muppets Theme song, or Andy Griffith ( I didn't know she liked that until she heard it on TV and came running ) Gracie loves Leather work and thinks she is my Assistant. As a hard rule, she is not allowed on leather and she is very careful about that. When I cut leather, she sees the tools come out, then knows she is invited. She holds it for me and knows exactly how much counterweight is needed to cut, (especially fringes, her favorite). She sits still as a statue where I tell her to hold it for me.
I don't know why she is such a worker cat; she also takes watching flying insects very seriously, and has saved my life more then once~ IF a wasp ( I am deathly allergic) gets in the house, she literally chases me into a room biting my ankles until I can close the door while she dispatches the beast. She could care less about spiders.
Gracie has short hair but when I comb mine, reaches out and grabs my hand to pull it toward her. She has to be combed, too~
They just want to do what we do.
You need a bigger place with more closet space !
