For this spell to find a lost cat or other small pet, you’ll need the assistance of a tree, rock, or other outdoor entity—preferably one in your yard or very near your home. Take one of your pet’s favorite toys and some pet food to the tree. Tell the tree about your pet and that you are concerned because of how long he or she has been missing. Ask the tree if it will help you by providing a beacon for your pet to follow to get home. Leave the pet food near the tree. If a small rock gets your attention, bring it and the pet toy into the house. Keep them near the door. Every time you pass the toy, thank the tree for its help in providing a beacon for your pet.
