You probably have things to hand that would make safer, yummy treats. See my recent post here:
Yummy natural treats!
All you have to do is crush these up into a powder, bind the powder with a drop of water and make them into small pea sized treats. They can be left to go hard or fed within minutes of making them up. You can add in a small piece of science selective hamster biscuit too or even a small sprinkle of dry porridge oats. x
