The primary reason cats are given up to animal shelters is unfulfilled expectations, reports the American Veterinary Medical Association. You may have wanted a lap cat and instead brought home one that prefers to prowl, or hide. Or you may have fancied a retiring cat who pretty much just likes to lounge, but got a boisterous one instead. Thats why you really want to make an informed decision when deciding on a new feline. Choosing completely on impulse rather than on some knowledge of the cats temperament wont serve you, and it definitely wont serve your pet.
