Hi, one of my favourite diy hamster projects is to blow up a balloon and then using a flour and water glue mix cover the balloon with plain paper. When dry pop balloon and either cut a hole for an entrance or use the hole were the knot of balloon was. Then customise paper mache with pet safe paint or wrapping paper which the colour doesn't run off when put under running water. I hope this diy helps someone. PS i didn't come up with this.
