Personally, I think that it isn't fair to have cats indoors all the time because cats love to go outside. With some cases, it is differant. (blind, deaf, declawed) The same with outdoor cats. If you are going to have a cat, at least let it come inside once in awhile. My cats come in and out of the house as they please, hunting and basking around in the sun outside as they were meant to be. Some people like dogs better because they think cats are boring, those cats are bored because they are inside all the time, with no other choice. Would you rather be locked in a house your whole life, or live life to the fullest? I think the answer is clear. Please don't get mad if you keep your cat indoors, some have your reasons, but just be aware that cats were meant to live how they please. They should at least have a choice. If your scared they'll get lost, microchip and collar them. They won't run away never to be seen again as long as you care for them. They might be so happy, they'll leave you with the "present" of a dead mouse. It is a honor to recieve one.
