You read my mind. I literally had the same thought about lying to say that I own him to get him checked/clipped.
As hard as it sounds. I absolutely would not do that.
It is absolutely awful that nobody seems to be able to give that piggy veterinary care and I do not think that this situation sounds fair at all, but are you willing to potentially get into trouble with the law by lying? I’d speak to the shelter and find out the exact situation surrounding all of this.
If there is going to be a (court) case, then surely professionals should have taken photos of his condition to show in any potential legal case (Thereby meaning there is evidence of his state even after his condition is cleaned up and treated?)
