I usually buy mine by the month, so some months they get shedded wheat, others cheerios etc.....
One of my chins will only eat oatmeal.

She's 15 so I give her her own way.

They all get a tiny piece of fruit and a pinch of cereal every night.
Looks like a lot when you have 4-5 chins in the one cage, but they all manage to get their share.
Thanks, Debbie!!
As you know I am not in the same country as you are, can you pls provide me exactly the brand and style of oat that you are using for reference? So that I may seach it out rather it offer in our local supermarket or not!!
Same as you, I also agree that the way when feeding somethings that are out of their regular diet should be base on a period by period basis, but not all the times, thanks in advance!!
