Talismans include bags of rice, sesame seeds, coins, and a tomcat (for happiness and fertility). The cat doesn't have to be a gift, it can be someone's pet that just hangs out in the room for a little while, emanating energy. The one caveat is that the cat may not be neutered. It defeats the purpost of the spell.
Note: This may be a good opportunity to adopt a stray from a shelter and let it participate in the ceremony prior to neutering.
