What's my favourite reason to kill an animal on the SPCA's list? It's so hard to choose. One minute I think it's #35 'Kennel crazy'. The irony is creepy since it is the SPCA's own misery and madness-producing cells and cages -- straight out of the 19th century -- that cause animals to go crazy.
Then I think, No it's got to be #15 'Ear mites'. AAS always kills any animal with ear mites; not because they're untreatable, but just because we don't like animals stupid enough to get ear mites.
