Animals get put down a lot of times because they’re too ill to have a good quality of life anymore. It’s like ending their suffering and allowing them to move on, maybe that’s what he enjoys. Helping the animals not feel pain and illness so bad they can’t really live as normal.

My last cat had to get put down because he had bad cancer and tumors all over his stomach and couldn't eat anymore. The vet said keeping him alive any longer is cruel and he should be put down. Throughout his life, he always hated the vet and avoided his little cage like the plague when he saw it that we brought him to the vet in. On his last day, when we tried to get him in to be put down, he just walked in right away and just sat there without any fight. Something about him just felt like he couldn't take the pain anymore and wanted it to end. It's sad, but sometimes they have to be put down due to health complications. They tend to be quite free spirited and when their health is so bad that they're on constant pain, it's sometimes the right thing to do.
