It's not that unusual, they pee on their food to protect it from being stolen!
Most grow out of it but it can be caused by over cleaning & removing the food hoard when you clean.
One way to help avoid it is to not use a bowl, scatter feed so he has to collect up the food & find somewhere safe to stash it, if he makes a hoard & pees on it just remove any wet food & replace it with fresh mix.
Poo isn't a problem.
