I use cosmic catnip for Tiber's treat. "the most aromatic catnip ever grown" and your 8th month old would just be starting to like it, if she has the gene. some could care less. It says to give them a tablespoonful.. but i think thats a bit much. I just shake the tub and he comes running in, no matter where he is in the house. Then i just let him eat for a few mins, probally a teaspoonful at most. Other wise, i get soem of that cheap lunchmeat from the store, teh one that costs like 60 cents..... And i'll rip off peices of a slice of turkey or chicken. he loves those!
