Should I be worried about rat homicide?

Ok For a couple of months now, I have had 1 rat for about 5 months now. It’s grown to quite a big rat, mainly to the fact that he’s blind and he does nothing most of the time.
A couple of days ago I bought a new rat. Now every time the smaller one comes out of his house, the larger one either (I’m not sure)
a) violently plays with him
b) Tries to eat him
c) or tries to have sex with him
Either way, the smaller rat squeals quite loudly until it manages to escape. Should I be worried that it’s not going to escape and that’s it’s going to get eaten? It does really throw the other one round a bit. They’re both male.

When it can snatch the stone from the large rat’s paw, it will be able to leave.

The need separate cages. The blind rat may very well feel threatened by any other rat and is simply striking first or may feel the smaller rat is an easy target. Either way, they need separate cages.

Actually, homicide refers to murder of a human. Rodenticide is the term you should use in this situation. Either way, seperate them.

Did you name the cage “Thunderdome”?

I am pretty sure that two male rats cannot share the same cage if one has already been there and sees it as his territory. It may have worked if they were introduced at the same time, but it is too late now.

They need seperate cages.

Ok, this morning I separated the cage into two, with wire that only the smaller rat can get to. Whilst I was doing this of course, they decided to get along and fell asleep beside each other. Now, with any luck, the bigger one won’t be fast enough to catch the smaller one while it’s eating. Well at least until I put in separate food containers.
Cheers.
