How should i properly introduce my new hairless rat to my adult one?

[Chez]

I have one hairless rat that is an adult and I decided to get him a friend as i know that they shouldn't be kept alone. After introducing them on mutual ground my larger rat scratched the new, younger rat with his claws by accident whilst investigating, the rats were left on the mutual ground and a I turned my back I heard a loud squeak, yet when i turned around neither of the rats seemed to have moved (older rat leaning on top of younger rat) although when (a few minutes later) I took the younger new rat out of the 'meeting' I noticed that there was quite a deep cut on his belly that was bleeding a little bit. When i say 'deep' I mean in relation to the rats size. My older rat is very docile so was this an accident and am I still able to keep introducing the rats and put them in the same cage in a day or two or shall I give up? Also, what shall I do about the cut on the rats belly? Thanks for any help.

p.s Both rats are hairless and the young rat also seems quite docile and is very easily handled.

This details how to properly introduce rats:

Try making a little rat vest/shirt out of fleece for your rats while they are being introduced. Fleece doesn't fray when chewed on so it is safe, and will protect their skin.

Also, hairless rats should really be kept with a furred buddy for warmth and such. However, you already got two rats so it's a bit late. Consider this if you get another one in the future.

Don't put them in the same cage straight away, let them sniff and see each other regally and they should get use to each other when you think the times right introduce them properly and put the younger one in the cage, keep an eye on them regally as anything could happen,if things get a bit to nasty remove the youngster straight away and just keep them in separate cages!
HOPE THIS HELPED
