Yes, I have heard that theory blondy. I believe Yoda was only about 2 or 2.5 lbs at 3 months tho, and he's like 7 now. But at one point we totally spoiled him with a bit of human food now and then and he ate a ton. So that might have made him a bit heavier. We were told by the breeder that he would be 4.5 to 5 lbs. We love our lil' Tubby just the same tho.
