Cats, dogs, and all pets need daily care and attention. They don't ask for much in return for their companionship but owning a pet requires a life-long commitment to feeding them, grooming them, exercising and stimulating them, and paying the vets fees when required.
Let's face it, you don't have what it takes to be a responsible pet owner. You're far too busy looking out for No.1 and you're shocked to discover that a dog needs to be walked EVERY day...WTF! Cats choose their owners, but your cat would simply choose to move next door.
