Isabelle Thanks for the suggestions. Be careful of the cat litter. I used to use it on one of my gardens and it almost killed everything in there. Someone told me it was very acidic (I think) and would ruin the soil. I also heard that animal droppings can have bacteria and other things that you do not want in a garden.
