12. Breeding
One very obvious (and lucrative) way to make money from pets is by using them to breed and selling the offspring to other animal lovers.
If your pet (especially in the case of dogs and cats) comes from a good lineage, then you could make exceptional money by becoming a breeder – as long as you are comfortable with the idea (letting go can be hard, you’ve been warned), you can sell puppies for an average of $400 to $2,000 a pop, for example.
But we must stress, there is a lot of responsibility that comes with breeding – and you should never only own an animal for the sole purpose of breeding with it – so make sure you research responsible breeding before you get started. Do everything humanely and by the book.
