It's a concern but not an emergency... yet....
I just got a betta fish
I also have 3 cats. (adorable little beasts)
Anyway I'm sure you have figured it out
Only one of them has taken to sitting on the arm of the love seat staring at my fish with a look of *suuuuuuushiiiiiii yuuuuuummmmyyyy*. I have school so I can't chase him off during the day.
I could probably put him up higher but he's so pretty on the mantel.
I think it's the movement that attracts the cat so right now i have some cloth covering the sides of the tank. At least until Elvis forgets about the fact there's a fish in the house. Does anyone else have cats and a fish? Tips? Hints?
