I need some advice

I have been having a problem with my 2 y/o himalayan/ragdoll cross. He has been getting into the filter of our fish tank and pulling out the pouch of ammonia remover pelets. Then he tears open the pouch and spreads them all over the livingroom. Has anyone else ever seen this behaviour? What can I do about it? I would appreciate any info I can get.

Hmmmm...the I dont have an aquarium but I have plenty of stuff they like to get into. You might want to try lining wherever he gets into the tank with coffee cans filled with something that makes lots of noise. That way when they fall down, it scares him off. You could also try putting some double sided tape where he has to step to get up there. Then theres always what I end up doing...make it so that they cant get to it all if possible.
