They can sleep whenever they want. They don't pay bills and they certainly don't have a J.O.B. Cats are subjected to stress, but it can be like pulling teeth to find out why? Why are cats stressed , and how could i know? How hard it is to get them to the veterinarian. How some hide when strangers visit!

Remember cats are territorial, and they can get stressed when new faces come into its domain. Don't expect your cat to be to happy about the new feline companion you brought home. Next thing the cat knows, a dog is curious about his food supply.

Be observant  ,and watch for changes in your cats behavior. Spaying is the most common behavior problem.
