Servals are not expensive to feed and litter box train just like any old tabby, maybe better. In captivity, they can live up to 20 years. Although I usually do not advocate altering an animal in the case of pet Serval, the front and rear claws need to be removed at an early age, around three months. Now, imagine forty pounds behind claws that can bring down rabbits and baby antelope. Better safe than sorry.
Servals get along fine with other animals if introduced as infants.
Xena especially loves to play with Kevin, our pet rhesus. Our two new kittens get along good with the litter of Boston Terriers, our litter of Chihuahuas, and our Yorkshire Terrier pups. The pictures on this website are of Xena at 6 months of age in my arms. Gabrielle and Callisto together and individual pictures of each. The kittens were born in late September and are only about 4 weeks old.
