Any idea of what they are

So we had a litter of rats from a double Rex male and a Rex female. Well every baby has a short tail. Parents tails are normal. Here are a few pics. They are not good. I couldn't get them to hold still.

They were most likely bit off....
Unless....do you know if they were born with their tails like that?

It looks like the tails got chopped off....=\

I can see one or two getting tails bit off but what are the odds all of them got cut off, unless it was some gruesome prank :O

Looks like they qualify as really good food :P

*on a side note, the last one looks like a standard coat, which isn't possible in a double rex X rex pairing, am I seeing the coat wrong?

Let's hope the breeder isn't trying to make short tail rats by docking them. Some dogs have their tails docked and ears trimmed. It's an artificial look that is man-made and never necessary except to please a human. =\

This was an entire litter born this way they didn't have tails at birth and no there isn't any standard coat it just looks that way in the pic.

Very odd. When in doubt - feed them off.

I have breed rodents for over 15 years and have never seen anything like that. There are rumors of tail less rats that are born that way but most people have found that they being cropped like somebody else had said. To me these look like they where cropped or bitten "to Soon" becuse they was still enough time to grow a bit more. Rats need there tails to control temps with heat and cool temps. I would just feed them off. imo. The other reason they could be this way is that they are sick aswell...

While they look bitten/cut off, there is a lady in Texas that has been working with curly tailed rats, she calls them "doodle rats".

So if they were for sure not born with tails, and have the bobbed look it could be a new type...

Manx can cause this.

Well we DID NOT cut them off. So for the record stop with the whole cut off thing. Could they have been bitten off, maybe but the whole litter?!?!? Also I'm not cutting them off to try to sell then as something they are not.
Also you are correct on the last pic. He is a standard coat I'm sorry the mother was a standard and father a double Rex. ( sorry it's a 1.3 group and they are all Rex or double except the one female not to mention she's one of two standard coats in that entire rack.)
So I posted the pics for ideas of what could be going on. So any ideas other then mutated as pinkies would be great lol ;)

Doesn't double rex + standard = all rex babies?

Well not sure but she is the only standard coat in the tub and the male is a double Rex. Look I dont really know much about rat genetics. I just pick out what I like and breed them together. So please don't imply like I'm lying. Obviously if I knew what the heck was going on I wouldn't of asked here. Our passion in breeding BP. We have our own business starting up so I would be lying or scamming with rats and risk messing it up. We have a great rep here in Ohio and on fauna as well. So I'm not lying im simply telling you what I know.

What's going on is the double rex may not be the only sire, or wasn't the sire at all.
As stated double rex to a standard coat makes all rex's, so it's not possible that the double rex was the only male to impregnate her.
The tail issue is probably a genetic defect with the clutch, I would never think you cut the tails off :O

Well she was a pick up from a pet store. When we got her they had just weaned all the babies.

That's crazy looking, whatever they are! Maybe some of this in the mix as far as genetics? http://ratsforpets.blogspot.com/2008...s-of-rats.html

I'm a completely moron with rat genetics I'm such a noob with them, so I won't even venture to say a guess as to what the heck caused that. You could always pull them out of your main breeding collection and work with them as a group to see if it's genetic or just a fluke. Or just feed them, lol! I'm interested to see what comes of this as far as answers...

BTW. Eww On the "doodle tail" rats.

Manx gene can cause a varying amount of "missing tail.

I'd hold them back and breed and see what happens.

If you don't want to, I'll take them all off your hands ;-)
