Maybe about 1.5 weeks? We only got him about 3 weeks ago and he didn’t have that discoloration at the pet store. Photo attached of when we got him for reference (although that’s the other side)
Jumping in here as @letterkenny’s wife and Rainy’s mom haha. @MissSkittles thank you so much for responding. I’ve been monitoring it and I think it is related to his color changes because he actually has a similar spot on the other side and I see the one originally posted change size. That being...
