If the Society For The Prevention of Cruelty to Animals is that loaded with $$ as to fly 200 beasts into Houston, in light of humans needing a ride out of the shit they are wading in; well, words fail...
The Caymans are a different matter. The people there, while suffering great devastation, are not wading in excrement.

You probably roast kittens and stew dogs in your spare time.
