I can see the opposite view of my own, and can respectfully disagree with it. Leopard Geckos can live around 25 years. Are you physically going to keep that gecko for it's entire life? If not, how in God's name are you going to 100% guarantee the person who agrees to "not breed it/pet only" won't breed it out of stupidity? Or won't give it away after a couple years without passing on the pet only rule, even if they did, how can you guarantee that gecko's life if it's being passed from owner to owner, as most Leopard Geckos do? I feel it's wrong to put off responsibility. I keep all of my healthy deformities until they die. Even if I had to give away ALL my geckos, I'd still keep those I hatched with issues.
*I too work with a rescue. The Rescue House, it's a cat only rescue. My current cat the ASPCA deemed "unadoptable and dangerous". She was on death row at 9 years old. TRH adopted her, and I adopted her quite a while after she's been in the system. She'll be 11 in September. I'm her 6th house according to her microchip, not including fosters/rescuers. I see cats come in in all kinds of shape. The worst thing is when they declaw them. Poor babies. And outdoor cats? Why would they do that to them? Flea medicine? POISON. Hell even yearly vaccinations are KNOWN To cause cancer! The pros/cons of vaccinating, the cons are significantly worse than the pros! Oh jeez, and the food some people feed their animals! Meow mix? Friskies? Fancy Feast? READ THE LABELS! My cats only receive Wellness CORE at our center, and their wet food is a raw diet. If I could I'd get the cats at the center 100% on a wet food only diet, since it's the healthiest (dry food is carbs, low moisture, and makes cats fat), but you can't let the wet food sit down very long, so we're forced to give some dry food. /rant
