I am a vegetarian and love all animals. I adore fish; the fact that they beg for food and seem to show emotions! If I can make Jax (my cat), me, and fish happy, it's a win-win all around! I just wish I could get Jax to do water changes. I'd bet he'd drink the fish water, though! Back in the early 70s, the hoods were metal and had to be pulled back entirely to feed the fish and otherwise maintain the filter, etc.- allowing naughty tabby cats great opportunities if the fish-tank supervisor slipped up. Thank the fish god that designs have changed. Look; don't eat or go fishing, kitties!
