Hi again!
I am taking Edgar to the vet tomorrow morning, to get a check up, find out if he is neutered and get some shots.
He hasn't left my backyard for several days, so I think that he is making his wishes known!
I think that one more cat won't be a problem, and I certainly am able to care for all the cats I have now. I am really lucky too, my boyfriend loves cats, and he met Edgar last night, and actually said to me 'Can we keep him?'
Thanks again for the advice, after we get back from the vet tomorrow, Edgar is going in a spare room in the basement until I get the ok from the vet to introduce him to his new brothers and sisters.
I also agree with Glacier, my cats hardly blinked when I introduced Freya a few weeks ago, there was a little hissing but I think they are pretty used to new additions by now!
