I have an 8 month old calico that just loves our paper shredder. Every time she hears me shredding papers she comes running and bats at the shredded strips coming out of the feeder. I have found that I must dump the shredded paper when I am done or she reaches in and drags all the paper shreds out and bats them all over the house. Now it has gotten even worse as she has taught our other cat to do the same thing.
