I have two cats and three dogs in my house. Harley and Sweet Pea love to sleep with my cats and whiskey loves to chase them around the house and pounce on them and chew on their ears till they howl!!!
I got my daughter a 6 month old male cat(Mr. Cuddles) from the American Humane Society(already fixed) for her birthday in April. Then my youngest dtr. wanted her very own baby kitty so I got another male kitty(Mr. Kitty) a few days older than Whiskey. He just got fixed himself. Anyway I brought Whiskey and Mr. Kitty home the same day and they think they are brother and sister they are always up each others butts!!!
I have never had a problem with either cat clawing or biting my dogs they all just play and snuggle together all the time.
