Feral Cats

Hmmm... seems we're now up to four feral cats in our backyard.  "New Toot-Toot" appeared tonight.  This little lady is a spitting image of Toot-Toot, but just a tad bit darker.  NTT also appears to be rather round in the belly as is Toot-Toot.  I'd love to do some sort of spay-release on them, but we can't get anywhere near them without the cats scattering to the winds.  Toot-Toot is the least scared -- she'll actually stay on the porch (within about 10 feet of me/kids) when we put the food out, but the others go a running.  I'll bet with some patience and treats, I could get Toot-Toot to come around -- but with only 9 days left, I don't think I'll have the time!
