Letting go is one of the hardest parts of fostering, but providing you did a background check via their vet etc. please take it easy on yourself. I consider myself a stepping stone for the ones I rescue, and sometimes get very attached to many of them, but as you and I know, it makes more room for other kitties in need, and there's a never ending supply of them. The only ones I hang onto are special needs kitties, though I'm at my limit and then some. It would be wonderful if Lucky & Chance's new people join PT so everyone can have updates. ((((HUGS)))) It's a tough letting go.
