My cat's def after some fish! Saw him eyeing my betta today actually. I'll look into the net, although I think that would be a little ugly. Maybe some catnip on the other side of the garden lolDutchAquarium said:It depends on the cat i guess, if we wants a fish or not. I've seen some people putting netting over their pond, the same you buy for leaf guards in the fall. They say it works well. I've got coyotes around my house also, and they do a very good job keeping down the cat population.
