Our first syrian hated sand! He had a little sand bath/salt pig style and used to remove all the sand so he could sit in it and get very cross if you put sand back in it. He did like the bit of sand in his potty though and would sit in the front half for a wash and pee in the back half. Ensuite bathroom
They can be lazy as well - why go all the way over there to wash when you can wash and pee in the same place - lol.
