I know, well spotted, guess their tummys weren't so keen on that color. They were all a bit harder than normal too.
The thing I find incredible is that it goes out the same order it went in but if you watch their tums after they have eaten and as I understand it their intestines actually push the food backward and forward unlike ours, so how does it not get mixed up?
When I broke them apart there were the same color specks of undigested color inside as there was on the outside.
I did laugh, I must admit but it was such a shock to see that in their litter tray:lol:
