Hey all! I have a bit of a dilemma and I would like to get some insight. I have read countless articles about keeping your cats out of an aquarium but my problem lies with the actual filter, not the tank. My babies are fine with not getting in the tank (although they love to watch the fish) but they love to pull the cover off of the filter, grab the cartridge out,and rip it up. They spread the carbon granuals all over the house. They get soaking wet doing this but it doesn't deter them. I literally cannot keep one in there longer than a couple of hours. Has anyone else had this issue? Should I worry about their contact with the filter? Any advice would be so greatly appreciated.
