I am glad you asked still in Adar!
why do you need labels on seeds for the gerbils? Gerbils might choke on the labels.
are you afraid that some goyim or sephardim will substitute kitniyos for pumpkins to save money or test your faith – similar to chalav akum? we do have a long tradition of chalav akum, but do not have such tradition regarding pumpkin akum, at least I don’t.
