Sounds to me like someone just trolling to make trouble. Or someone who just beleives everything they've ever read on the net, so they'll post this sort of 'warning' to prevent anyone from allowing their precious unwanted puppies from becoming snake food, thinking they're doing a good deed.

While I can see people's points that rats can be just as loving a pet as a dog, and indeed, rats are bred exclusively for pets by some rat fanciers, there is the fact that to most of the population, rats are lab rats, or pests.. dogs are pets.

I would never ever advocate feeding any age cat to a python, as a cat could kill the reptile even if it only bit once and caused a major infection. Plus the whole "fuzzy pet" bad publicity.

I myself wouldn't feed pups or kittens to my reptiles. Just isn't a really good idea PR wise. But I also freely admit that they're just animals, and I don't think it's evil that other cultures eat dogs or cats. We eat goats and cows and chickens.. other people eat goats, but not cows.. vegans think it's evil to eat any animal. Shrug, different strokes for different folks.
