I make catnip sockies for my bunch. Just take an old sock (clean of course) and put some catnip in and tie it shut. If there is a hole in the toe, just tie it there, add catnip, then tie again. I made the mistake of only making one the first time because my "senior citizen", Leroy wouldn't want to play. Was I wrong. He zoomed out from behind the furnace and stole it from under Chester and Leroy's noses. I wised up and made one for each kitty. I had sockies flying past my nose while I was on the computer. They loved to throw them. Funny thing, when they all pooped out for a nap, Leroy had all the sockies and was sleeping with them. Never count an older cat out, huh?
