Sylvia, I did trap, neuter, return a long time ago. Problem was, one of the cats had just had kittens a bit before so there were 6 kittens the neighborhood kids found and came knocking on my door cause they knew we fed the cats! So I fostered the kittens for awhile. My son took two, I kept one and found homes for the others. Now, at this house, I think someone keeps dropping them off. I found a home for one but have had to take two into the shelter. Our cat is indoor/outdoor (of course, since he's one of the kittens born feral) and the other cats keep coming inside! Finally had to get the kind of cat door with a magnet.
But on to catmint, Deb, I have it everywhere if you need some! Believe it or not, I was selling cut stuff at market, a huge bunch for $1.
