So far after 2 years they haven't. I mean these things must know I wont let her in. It is like they taunt her LOL. they swim all over and put there butts in her face. The pic there was taken while she was staring down the fish. The fish win lol.
Do your cats ever jump on top of the tank? And can it take it? We bought fish ages ago for "kitty TV." They only seemed to enjoy watching the fish swim around from on top of the aquarium, and we were so afraid it was going to break! When we moved into the house we ended up putting it up on a stand - and now they just ignore the fish.
This chick thinks she owns everything. She has that green chair you see there it is hers I bought it brand new off the Lay z boy auction for 30.00 because it is missing an arm. But she loves it and I dont sit on her to we work. LOL
