Toilet Paper Rolls
You don't have to be able to afford the "designer" hamster supplies. There's always the off-brands! Bedding can be quite expensive, so brands like Boxo, Clean and Cozy, and even Wood Based Cat Litter are always an option. That being said, don't purchase any sketchy brands you found at your local walmart. Used trusted brands or brands other have tried and have had good reviews on.
Empty toilet paper rolls are commonly thrown out or recycled and never reused. Little do you know, these can actually be used for hamster toys! As long as they are in decent condition (not wet, dirty, or haven't been in the trash) they can be used as toobs for hamsters. There are many tutorials on Youtube for simple hamster toy crafts made with cheap, and sometimes free craft supplies!
Not all of us are swimming in dough. So here are some cheap ideas for your hamster!
Good quality hamster cages and tanks are quite expensive. You can actually D.I.Y your own hamster cage!
