Ashley, I just posted to your other thread, so I mentioned this there as well.
Don't buy your new kitty from a pet shop or pet store. Also, be very cautious with those tempting newspaper articles, such as "Free to a good home" or "Kittens, $5 each." Your best source for adopting a kitten will be from your local shelter or rescue organization. Many of these cats and kittens come with personal histories, and would LOVE to have their forever home with you. Purchasing from a backyard breeder or pet shop is only contributing to the cat overpopulation problem, and how sad, considering the MILLIONS of cats that land in shelters each day. Many of these babies will be euthanized, or will spend the rest of their natural lives without knowing what a loving home actually was. PLEASE GIVE ONE OF THESE SPECIAL CATS A CHANCE! They are eternally grateful for that second chance at life and love, and will rarely let you down!
I would be more than happy to point you in the right direction...PM me if you want me to help you search some shelters and rescue groups in your area.
Also, there are some considerations to make when talking about kittens vs. adults, which others have already shared.
Who doesn't love a fluffy little kitten??? They're cute, small, silly, active, wild, curious, and a whole gamut of things that are special and enduring. We all love kittens! If you prefer a kitten...shelters OVERFLOW with them, especially in the spring and summer. I would definitely recommend that you adopt two kittens together, if you prefer to adopt at a young age...they will drive you far less crazy when they can keep each other occupied. Littermates are always a good idea. Often, shelters are so full of kittens and cats during kitten season, that you can adopt 2 for the same fee as one cat normally. And for you, two cats will NOT present to you much more cost or work. I have 3 cats, and I honestly don't pay much more to feed and care for the other two, as I did when I just had Fergus alone.
Please consider an adult. Cats can live a very long time...up to 20 years! If you adopt a cat between 1-5 years of age, you still have a loonnnngggg life to share with your pet, as these are still very young cats! Adults tend to be passed over in shelters...everyone is itching for that tiny kitten! But, because of the unpredictability and craziness that a kitten can present, the newness wears off, and many find out just how much work a young kitten can be!!! Perhaps, as they grow, they don't quite "get" the litterbox thing, or their temperments are not quite what the owner expects...sadly, these kittens are often returned to shelters, as there is NO WAY to predict what type of adult your kitten will grow to be! When you meet the adults, you are looking at a longer adjustment period into your home, but you know exactly what you're in for! Some of the greatest pets I've ever owned were the adults I adopted from shelters...they so much wanted that chance to prove to SOMEONE that they deserve that second chance at a forever home.
