Coco expands on the observation that dog heaven and cat hell is the same place:
In dog heaven there are self propelled furry chew toys that make little meowing sounds. In dog heaven, the chew toys never wear out.
In cat hell, one is subjected to unending, bone crunching torment for eternity.
Hence, dog heaven and cat hell are one in the same.
PS: those questioning the innate evilness of cats should ask: Why are there cats that look like Hitler?
Kitlers, they call 'em.
Coco is wise. She knows instinctively that cats need to be chased.
