Suprise no tail

[Boxerblue25]

I was cleaning my rat tubs today and what do i see a tailess rat. I didn't notice him before (its a boy). Dont know if this is genetic or not but im keeping it to find out. What do you guys think was it born like this or the tail was cut off

I would say it was born like that. Looks cool though. Thanx for sharing.

Manx rat. They pop up from time to time in my colony, but I've never been able to produce one by breeding back...

The shape to me, looks like his tail was bitten off or injured as a baby.
