I see this all too often when I check in the Pets section of Craigslist: 'Free dog/cat to good home'. While I'm sure these people really want to find their pet a good home, there is a danger to posting free pet ads that many don't know about.
Some people look for "free" animals for these reasons:
- Food for their pet snake
- Bait for training dogs in fighting rings
- Breeding stock in puppy/kitten mills (for dogs or cats that aren't spayed/neutered)
- To hoard and neglect
- To use for research purposes
- To perform cruel acts upon the animal
