No. I adopted the one, fixed her and she's now outside cat. On extremely rare occasions I feed the other one that visits her - I think it's her brother because I found both under the hot tub when it was cold last winter.
I started feeding both then a big gray was spotted and another black, then a yellow. You feed one, they all come. Fortunately haven't seen the other ones at all in about 9 months.
If I had the money, I'd take every stray and have them fixed.
You have to catch them first. =)
You have a good heart :)
