Hello Dayna. I agree with Gonzo, diets are no fun! However the two treats you mentioned 8 in1 Yogi's and Ferretvite have a lot of sugar. I would worry about future insolinoma as much as excess weight. I would suggest finding a new treat like 8 in 1 Ferretbites or Bandit treats and using Ferretone instead of Ferretvite (same company). If he only likes Yogi's than you could try putting a healthier treat (like Totally Ferret's) or a different kibble into the Yogi jar so it gets a Yogi scent or coating, then give him the kibble - he'll think it's a treat! Good luck! Risa PS two of my three fuzzies gain weight in the summer instead of the winter. They have their cycle's backwards. I was told it's because of when they were bred.
