Bully cats
Cats are territorial animals and will fight for their space. I believe that when cats are pets and are exposed to constant love, they become softies :) On the other hand, cats that are born and "raised" on the streets tend to be tough. When pets and streets cats get into fights, guess who is going to win? Your pet can really get hurt in these types of altercations.
Diseases
Although your cat may have all vaccines, and have current and regular visits to the vet, being an outdoor cat will expose him/ her to many diseases. Your pet can become ill frequently if constantly exposed.
Wild life
We all know that cats can be feisty little babies and will stand their ground... but if you share your habitat with wild life, then your pet can become prey. There are areas, even in the city, where coyotes and mountain lions take up residency which can be dangerous for your cat. A small animal like a cat can be an easy target for a hungry fellow.
Germs
Cats are clean animals and do a great job maintaining their fur nice and clean, right? But if your cat is an outdoor cat, he/she will be exposed to many filthy situations and can bring germs into your home. As an outdoor cat, one moment he/she can be ruffling through trash and the next caressing you (yuck!). Not only can outdoor germs be harmful for your pet but you as well.
Human
Humans! The most dangerous creatures of them all... your cat will be exposed dangers produced by humans. Your kitty cat will be exposed to cars and wreckless drivers which can hurt him/her pretty badly. Also, let's get real, some people practice cruelty towards animals. Cats are curious, feisty, and sometimes mischievous; we, pet owners, tolerate it all because we love them and most likely are animal lovers. If your cat encounters an unfriendly human, he might be exposed to physical abuse or chase/ terrorized away :( poor babies.
Making the decision to adopt a pet is an important one and there is a lot to think about before bring him/her home. This is just my point of view and hopefully it helped you make the best decision for you and your family.
In my opinion, cats should always be indoor pets and that's how Miss Missey and Mr. Fudge have been "raised" :)
