My manx does the same thing. Toys, stuff, lizards, anything goes in the water. She also has to drink running water. When she has made a “kill” she puts it in my shoe then goes thru the house making this loud throaty cry.
My other cat is sorta dumb, so he has been trained to heel, come, jump over barriers, run in circles if I tell him to. He does all the basic obedience work. Including running into the wall when I tell him to. All I need is my laser light.
The manx has taught him the basics of opening drawers and doors. (put your paws under it and move it back and forth till the latch pops.) So I have to have child latches on the important stuff. Sigh....... She does understand the principle of door knobs and I have caught her standing on her hind legs with her paws on the knob trying to work it. So far no luck, but who knows.
I have been taught to sit, stay. Sometimes a cat just needs a lap. I do what I am told.
“she goes thru the house making this loud throaty cry”
Our Siamese does that at night. She carries her small stuffed toy through the house doing that weird yowl from her throat. We thought she was telling us “it’s time to go to bed!” because it’s always around that time. But maybe it’s a hunting-related thing.
I've long been sure that the one wish, shared by every cat on the planet, is for opposable thumbs.
If that wish ever comes true, watch out!
