It's not a regular "THING ". They have the adoption fees 1/2 off right now. It's not so bad to pay $30 for a companion with microchip, completing vaccinated, dewormed, health checked and collar with identification tags
Its not on a set schedule. You have to wait until their advertised or call and ask them when one is coming up.
It was 3 weeks ago they arent free its already cost me 800$.
