karen -thanks! We have lizards around here too, they even find there way in the house. I always try to rescue them, but it has alway been for the lizards' sakes, not my cats. Now I will for them, too. The other day I had to rescue and relocate a caterpillar they were all bent on playing with, and I was concerned then that it might be poisonous to them. I will keep in mind that any other animal could potentially harm the cats.
