Hmm I understand, I fed my first BP in a seperate tub too, but I have since learned it is completely unnecessary.
Believe me, I did the same thing with my first BP, but just think about this, I have found the animals to be extremely addictive. I fully intend to own many of them in the future. I can't imagine the pain in the butt it would be to move each animal to a seperate feeding tuband back again.
Not to mention that I'm fairly certain the snake prefers to be fed in it's own enclosure anyway.
