You can get cat scratch fever from a bite or scratch from an infected cat. You can also get the disease if saliva from an infected cat gets into an open wound on your body or touches the whites of your eyes.
You can ask friends and family members if they have a cat they need to give away, or maybe a cat has some new kittens. Make sure you ask: what kind of cat, how old is the cat, cat health conditions, personality... Most importantly, ask parents for permission for the new family member to come home.
By adopting a shelter cat, you're giving a homeless animal a second chance for a long and fulfilling life. When you adopt from a well-run shelter, you are getting a pet that has been medically checked, evaluated for temperament and often already spayed or neutered. You'll also get a thorough education from an adoption counselor who will cover all the ins and outs of cat care and is happy to answer every question you can come up with. Adopting a cat from a shelter is a decision you will feel good about every time you look at your cat.
Many people begin looking for a new companion animal online, and this can be a great way to start your search. Lots of animal shelters and rescue groups have their own websites, where you can view their adoptable pets. Also checking out social media like Facebook or Craigslist is not a bad idea. Breeders also sell kittens on the Internet, but it's never a good idea to ship a cat to your home. Check locally and make sure the cats are healthy and in good condition.
