I touched the swollen part of his back, I can still feel his bones that’s why I’m not very sure if it’s tumour. It could be arthritis due to genes problem but I saw his black lump today while he’s drinking so that could one of the reason that lead to spinal problems. ( you could see the pic when he drinks there’s a small black lump under his chin). I did handle him today but he doesn’t seem like he’s in pain. He’s doesn’t squeak nor drag his legs. The only problems are his hunchback became so obvious the last week and he stopped running on his wheels. Besides that, everything seems normal. It’s so sudden and it hurts me so much
I really don’t want him to be in pain. I just let him sleep whenever he wants to as I want him to be comfortable.
