Sanitising is a great idea. They had a change of Auboise last time but if I can think of a way a good scrub down would be best.
I have milligram scales so can dose small amounts very accurately. I think last time they had a bowl of mash and shredded wheat for a treat just a couple of evenings but it was dosed too.
Just before I left this morning she had flicked half her ration on the floor but it's all she's getting so will have to pick it up again, silly girl.
