Maryanne, I missed what you're trying to eradicate? Ants? Roaches? There is a recipe for ants (the commercial product is Terro) simple syrup - 1 cup water, 2 cups sugar, 2 Tablespoons borax (and don't overdo or they ignore it). Don't let the syrup boil much or the liquid is too robust and ants walk across it, can't sip and take it back to the colony. And a question about your knee - are you drinking enough water? I wonder if retained water as the year gets warmer might be more noticeable after surgery?

Good luck with the new kitten, Michelle. I usually find that a new and younger animal entering the home energizes the older ones. It's good for them. (Did you ever read any of the James Herriot vet books? I remember a particular essay about introducing a young pet into the home and having an older dog that seemed to be fading decide to get up and eat.)
