"I think it is great to have so many interesting cats. My two inside ones, Momo and Baby, are weird. Baby has one eye because I got him when he was a kitten, his eye was infected and that is why I got him to take care of him. Baby is crazy, Pyrk can attest to this. He is also really talkative, and has learned how to play and steal things even with being at least 80% blind (vets tested his field of vision in his single eye).
Momo is fat and lazy, and demanding... and can talk... She says 'Mom', 'momma', 'out', 'water', 'but', 'help', a few others things, but the best one is 'bitch'.. She likes saying this when my 12yr old niece is around, I dunno why. Momo tends to get into tiny spats with Baby, cause he is still young and likes to play, and she doesn't want to at all, she is content being fat and lazy, lol.
Of my outside cats, Charlie loves attention, from anybody, and she is very accident prone. She's lost a toe and had to be confined inside for a long time, and she's also had issues of scrapes and cuts/wounds all her life, she is really adventurous and friendly. Priss 'Princess' is queen and demands others follow her rules. She protects the yard and everything, but the best thing is, she leads us to things. Like she was tracking a snake for us and leading us where she thought it was... Pyavi is a butt, she hates me, even though I raised her, she always runs from me if I walk over to pet her, and she glares at me all the time... If I can pick her up, she grumbles and squirms the whole time, to a point of hissing at me... B.Y.K. is a stray who has taken up to living in our yard and he's become part of the family, but he was abused before he got to us, so he always runs from us, though he does seem to love us in the sense that if we stay quiet and still, he'll walk to or near us without fear.
The best is the last one, Picert 'Princess-Squirrel' is so... weird. He won't respond if you call him prince, he is a princess and demands that is his title. When I lived somewhere else, he was an inside cat and would sit up on his hind legs with his tail curled against his back, he looked like a squirrel. My roommate then had a horribly loud cockatoo, and Picert hated that bird, and was deathly afraid of it. The bird ended up on the floor and chased Picert, and bit a small piece of his ear off.
About Taku moving the battery, I've seen cats move heavier things, it all depends on their willpower and why they want to move the item. Taku seems to really have wanted to in the laundry room, which is understandable. Cats have an intense attraction to laundry rooms.. Momo likes to try to climb in the dryer if we don't diligently watch the dryer when the door is open. Baby, who is about a pound, has moved the box of little, which is 20 pounds, just because it was where he wanted to lay.
