<human>: Can you succinctly summarize the text in 1-3 sentences?

Recently just saved two cats; both fat fuzzy guys one of which is 10 and the other 3. They're both really outgoing and the moment I brought them back to my apartment they were wandering around and checking it out and had no problem coming up to my GF and I for the pettings.

All last night (got them yesterday morning) the younger one bullied the older - not letting him leave from under the bed, and if he did he'd get on top of him and bite his neck.

So we're aware this is a submission thing determining the leader of the house, but is there anything we can do? The older one has a lot of trouble leaving from under the bed and he get "yelled" at when he does. Being an older cat we really don't want him to be so afraid all the time.

I think the real question is how far do we go in disciplining the younger guy but not get in the way of the natural order of things? Sorry for lengthy post too.
<bot>: Younger cat "bullying" older cat, not letting him leave under the bed and always putting him into submission. What do?
