I bred cats, but wanted to add my two cents here.
Before you even purchase an animal, there is lots of due diligence to complete. You need to invest time, money and really LOVE the breed you're interested in breeding. Also if you'll purchase a male or female, as it makes a HUGE difference.
But my suggestion is to not to breed. MILLIONS of animals are put to death yearly.
And frankly, if you're just starting out, you have atleast 5 years before you can actually call yourself a breeder.
