Like Sims, pets age in stages. A pet starts as a kitten, puppy or foal and ages to an adult. In The Sims 2: Pets and The Sims 3: Pets, an adult pet will eventually age to an elder, and will eventually die. However, in The Sims: Unleashed and The Sims 2 Pets for console, adult pets live indefinitely. In The Sims: Unleashed, kittens and puppies are objects, and appear as maternity tents topped by a cat face or dog face. The mother will watch them, but it is not possible to interact with them. Only adult pets can get pregnant, elder males can make an adult animal pregnant.
