i had a spiteful cat when i had my first betta. well, he wasn't MY cat, but my sister's. he liked to torment Zach, and taught my cat(a fat full-tailed Manx named Goldie) to knock his bowl down! caused Goldie to break the first one(thus, Zach lived in a Blue's Clues cup for a few days until i got a new one). i started keeping orange bag mesh over the top to keep my fish in, and keep the cats out! luckily, my black cat, Chloe, and my dad's old neutered cat don't give two licks about the fish. Junior will actually lay up on my fish table and sleep! my babies are all excited about this new creature laying by them, though!
