If you have a cat (or two), you may want to adopt another one (or two). However, be careful. Just because you like more cats doesn’t meant your cats will like more cats.
Veterinarians recommend that you provide plenty of safe spaces for all your cats to hide. Also when your current cat is with the new cat, be sure to lavish praise and attention to let your current cat know that he or she is still loved by you. More cats might seem like more joy, but ask the opinion of your current cat first.
