I have a rat with black and white color and black eyes yet one of her eyes has a red tint. She had babies with a black and white male and 3 of her 9 babies came our white and tan with red tinted eyes.
I kept two of the tan babies and both of them can't keep their heads stright and still. If they stop to stare or sniff the air their entire head and sometimes shoulders sway back and forth!
Now, their dad when I first got him would (honest to God) chase his tail just like a dog. So I thought maybe some of the rats were a little retarded.
Aside from the rats not being able to keep their heads straight, they're completely fine.
Has anyone heard of this? Are they indeed retarded rats?
