Its very hard sometimes to let them go but if we kept them all then we'd either have hoarding situation or get to a point without space for fosters! In the past two years I added two cats permanently to my home. I have four permanent cats total and it's my limit! They are trying to outlaw TNVR in my county as well, so we've been taking in a lot of feral kittens in attempt to tame and find homes for them. The ones that don't tame up are TNVR'd with a good luck and lots of crossed fingers.
