Mercury News | 06/27/2002 | Cats may be linked to sea otter deaths

Cats, nothing but trouble... Apparently, it's another one of those cases where "solid waste" contains organisms deadly to sea life, and the waste gets flushed down the toilet, and faster than you can say "that's what it's for", it's in the ocean. Otter experts say that you should bag up your kitty litter and put it in the garbage rather than flushing, and I know that's not going to happen.
