year, millions of dogs and cats are killed in animal shelters.
The cause of this problem is twofold: unaltered animals and
puppy mills. Many believe that it is not necessary to spay or
neuter dogs and cats. However, statistics show that one female
cat can produce 370,092 cats in seven years, and one female dog
can produce 67,000 dogs in six years. Spaying and neutering
increases an animal's life expectancy and reduces the number of
animals put to death in shelters. The second cause of the
problem are puppy mills---breeders who mass produce dogs in
deplorable conditions and sell them to pet stores for resale.
The female dogs are kept pregnant all year round and as a result
are unhealthy. They are commonly inbred but are sold at premium
purebred prices. CFA recommends adopting a pet from a shelter
instead of buying one from a store and spaying or neutering that
animal at the proper age.
