For every person that is born, 15 dogs and 45 cats are born.
Pet overpopulation is a big problem. As these statistics show, in order to help keep up with the current flood of puppies and kittens, every person would have to own two dogs and six cats at all times.
A household of five would have to harbor 10 dogs and 30 cats! Adoption alone is obviously not the answer. Desexing is. Please spey or castrate your pets.
