From what I read their differences can be from bone growth, genetic origin, and also from their habits.
I have two pet rats they're sisters, one is always active and is smaller, the other spends a lot more time sleeping and hording food. Other than that hope this helps! Like what is said above, I have two girls and one is smaller and sleeps more, one is larger and more muscular and is more active. It really just depends. Like all humans have different metabolisms and are taller and shorter than eachother, rats are different in size, muscle amounts, etc. too.
YES
It is possible, yes.
of course yes, because wild rats are bigger than chicks but it does not mean that if you are bigger than other animals you can eat them absolutely
Almost but the differences are that: Rats are bigger than mice as most people know. Rats are more intelligent Rats are less smelly Rats are much better pets than mice Related things: They have almost the same lifespan. Note : These are only what I know. There might be more answers to this.
No, dumbo rats are much bigger than fancy rats. They are both very nice creatures though.
Rats are nicer than mice and are bigger, live longer, and are smarter than mice.
Bigger than 1 rat. Smaller than the universe.
they are bigger than most rats and have larger ears that are set lower on the head of a normal or fancy rat and have flatter heads. they are also believed to be calmer and more docile than other rats.
A Rat, it has the same mouse tail, basically same everything, but mice are smaller, and rats are bigger, and male rats tend to be bigger than female rats.
No, they are never exactly the same. One of your feet is bigger/smaller than the other. Whether my a millimeter or a whole size, they're never EXACTLY the same. One of my feet is a 1/2 a size bigger than my other one.
You do them the same way as you "do" other fractions.
NO WAY! Rats are so much bigger than gerbils and could become territorial. Please do not do this, or listen to others who addvise you to. Please.
