he will more than likely be back. the toms especially un neutered will roam sometimes for days if not longer and then make their way back to their safe house. he's no dummy and many times you'll find out that you're one of 2 or 3 homes helpin him out. we're dealing with an un neutered 20+ pound grey/white tuxedo lookin kitty we call Chunkcat that showed up 4 yrs ago. he would be gone up to 2 weeks or longer at a time and we would think he was just gone or maybe had been killed, but he would show back up all raggedy and/or injured and let us heal him up again. most times he's a cuddly angel, but if he feels he's been crossed would just as soon shred some skin or give you some fang reminders of who's the boss in your hands. he seems to have slowed down a bit the past 4 months and hasn't wandered since last june. we're not sure of his age and wandering toms without human help are lucky to have a lifespan of 3-5 yrs. about 2 and a half yrs ago we also had a himalayan lookin female kitty show up with no front claws and hasn't wandered any place but the backyard since. even other people's cats like our house better than their own. handi-capped and injured cats and birds seem to find me whether at home or work and i'll help them all the best i can. i have the word sucker on my forhead that the critters see and unfortunately some humans too. your kitty may not come back, but you did the right thing by helpin him out at the time. be patient...he's just a busy wanderin man.
