hi-- hope im not being redundant. please feel free to point out if there is a specific thread existing for this. (with post #s please- i get lost in some of these huge threads) i want to use a variety of suitable stuff to build a nice litter. has anyone used a few red sumac berry flowers as a toss in for litter? theres tons of them right now how about just a handful or 2 of acorn caps? i think id like to pull some lemon balm and peppermint plants to add also. i'd like to make sure things are suitable. id love to hear your ideas ps whats this about adding "clay?"
