My grandmother figured out that the air can sound startles her dog. So every time her dog did something naughty, she'd spray the air can in the air to make the little princess stop. Now all you have to do is say the words "air can" and she quits whatever she's doing and watches you warily. It's adorably pathetic.
My cat is practically perfect in every way. Practically. She ignores the fish tank. If there's a lid it means she can't drink the special-flavored water. So she doesn't care about them. She's really just a water fiend. However, she's a good surrogate fish mama. She reminds me every night to feed the fish. The fact that she gets a share of the food might have something to do with that.

My kittykins at around three weeks. She was born a poor orphan baby.

Her today at 5 years. She only deigns to lounge upon shaped blankets. She prefers triangles, but has been known to accept squares and rectangles.
