I just want to "Ditto" Petzy & Sarita.
I've read so many times people 'rescuing' animals from breeders or pet stores, when in fact they have just supported them so they can fill that empty space with another animal to make money from. When instead, by refusing to help/buy from these places they will be forced to stop making more animals for sale, and then we can foucs on homing the already homeless in shelters.
Read lots, and get involved with local rescue groups. If you have not Volunteered with one before, do it before jumping in on your own. I've been Volunteering for many years now, and i can say i would never go out on my own to start a rescue, way to much stress/money/work involved.
If your anywhere near Vancouver BC Canada, We're always looking for volunteers
