Companion Animal Protection Society (CAPS) is a nonprofit dedicated to protecting companion animals from cruelty in pet shops and puppy/kitten mills through investigations, legislation and rescue.
"We've investigated breeders who have puppy mills without knowing that they had cats, or not being able to gain access to the cats," Deborah Howard, president of CAPS, told The Dodo. "If we don't get access to the entire facility, the cats would be the hardest to see because they are completely indoors."
Kitten mills that are USDA-licensed can sell their live products to the pet shop industry. And even in these facilities, cats "are crammed into dirty cages, covered in matted fur and sleeping in overflowing litter boxes."
CAPS sends investigators into kitten mills, and what investigators find "look just like puppy mills - but with cats. Mothers are bred until they drop. Kittens are sick and dirty. Cats are kept in feces-stained pens, with no physical or mental stimulation."
