She said she bought new cages

This girl lied about buying new cages when I sent the animals I was under the impression cause she said she got new enclosures if I knew she lied I wouldn't have sold them

If you had reservations about the ability of the buyer to care for the animals, you should not have sold them to her. Yes, she screwed up, she's a newb, they screw up, it's what they do. The point of an ethical seller is to set them up for success and that includes not selling to them if they do not seem ready. You were obviously suspicious that she was going to stick them in a 20 gallon, but you did not require proof of proper enclosure before shipping her the animals. I'm not claiming you owe her a refund or anything, I'm just pointing out the hypocrisy of your claims that you care for your animals more than anything while showing all the actions of a common, low level flipper.

Your insane

It's not her fault cause she lied and killed them it's my fault cause I believed her and sold them that's insane. She will just do this again

I had no reservations I believed her

If she did indeed stick them in 20g tanks, that is what killed the larger one & will likely kill the baby.

Keven, in the future, I'd require pictures of the setup before shipping, especially if they have already bought the wrong size.

That is a very good suggestion and I will definitely incorporate that Into every sale of uromastyx from now on. I just didn't know to do this. Thank you for the suggestion

I'm seeing pretty clearly that this is not his fault, so no need for the witch hunt. We have screenshots of him trying to help her provide proper care and no evidence from her that she ever followed it...at least not yet. Until she provides proof that she wasn't housing them together in a smaller aquarium, she looks to be responsible for the issues.

were the uros rescues or were these animals purchased for resale to fund your rescue?
