In the past, he's plump and cuddly like the 2 photos above. Now, he's like this
If you take a good look, there's a 'dent' near his hind leg. He also bit a huge chunk of his fur away from his tail. The vet says that he's under stress but there's no changes in the people, the home or even his food or treats. Everything is the same. I'm not sure where the problem is but I'm sure my baby's in agony. If this carries on, I'll have to bring him back to the vet. I hope and I pray that he'll get well very soon.
