Bless!!!
I'd either hide a few for him around the house to sniff out later or make him a dreamies dispenser toy. Get a large smarties tube (sadly you will have to eat the smarties first) Cut a few holes in in, just a bit bigger than dreamies and seal both ends. Pop dreamies in the holes and let the cat find them. My two are so funny with it, Izzy noses it along the floor until a dreamie falls out, Cashie will whack it soundly with his paws.
Anyway, it means they get their treats but have to work a bit at it and keeps them occupied for at least two minutes!
