My dog ate my rabbit...?

im sorry for your rabbit. but no i dont think your dog will kill your cat if they have been introduced and shes in the house. my dog is the friendliest dog and loves my little kitten to deeath. but when my dog sees a rabbit outside....she goes crazy after it.. i mean unless your dog is very mean and aggresive, you probably shouldnt even have it in that case. and if it does kill your cat, it should be put to sleep
