I am so glad to hear all these stories of cats as evil as mine!!!
However, when you get those plants to the testing phase, FrenchHen, I would be glad to volunteer to test them. I mean, I love my cats, but it would be for a good cause, after all.
Poor little Tuna probably saw someone besides me when she made the "evil eye" look.
She thinks I am the most wonderful creature ever born and thinks all other humans are evil, nasty and worthless.
If I am petting her and someone walks by she stops purring, jumps and bites them, and is immediately back under my hand purring. LOL It's really funny. One day my 9 y/o hadn't been feeling well. Gem, which is his favorite cat, walked over to love on him. Tuna slowly walked over, bit his arm and left. He started laughing and said "Gem came to tell me she hopes I get better. Tuna walked by and said I hope you die". LOL
