new rats

well, i just picked up some bigger rats for rex. their the stores "Adult" size, thier about 3.5-4 in long. i have a question. how can you tell a rat from a mouse?

size, shape, tail.

I'm just gonna move this over to the feeder forum. :)

thats one tiny little rat man. definitely not an adult.

Rex,
If you have had your bp for any amount of time, and it is eating rats, you should be able to tell a rat from a mouse. Mice are TINY little things, even what they call a jumbo mouse is easy to tell the difference from a rat. A mouse looks more fragile than a rat- they are much smaller, has a thinner tail, its facial features are tiny. Rats have thicker tails, their noses are longer... what they sold you was either a big mouse, or a very young rat... can you post a pic, it is very hard to answer your question without one seeing as though a description can be hard to picture when it comes to rodents.

It seems to me, that baby rats have a larger head size than adult mice do. Also, a rat would have a thicker tail. It's pretty easy to differentiate; if you need photo references, just Google.
