I have had 3 catahoulas, they were excellent guard dogs, great buddies, dang good workin dogs, adn would kill anything cat size adn smaller...in my experience, working dogs are NOT good around small critters, as they have the drive and herding instinct, and if it doesnt herd, it gets bit, and if a dog bites a bantam, thats all she wrote....but I loved the catahoulas I had, awesome workin dogs...
