i have a ?

i had found this all white card board box.i had cut out two pathways since it will be in the corner, away from any drafts. and i wanted to paint a nice scenery on it, but i was wondering if anybody has used paints on anything that will be in the pen with their piggie? and what type of paint did they use?, i was thinking of using the crayola paints since the package says non toxic, but what might not be toxic to us might be to a piggie (ugh, i'm so frustrated ). any help would be greatly apreciated =0).

I don't know what kind of paint you could use but I have an idea. If you aren't too worried about the colors bing bold you could use water and food coloring. I'm assuming it is safe since it is safe for humans but I do not know for sure.

Food colourings can be harmfull to humans. My son cannot eat most. Don't know if they would safe for pigs but the vast majority you buy are artifical and some are even made from oil

You should eb able to buy pet safe paints and varnish from diy stores
