The tent I bought from Amazon was about $20 or see if anyone you know happens to have one laying around. You can also try sitting in a dry bathtub with them and close the shower curtain so their forced to interact with only you. Just make sure to remove any harmful items and close the toilet seat an door just in case. This has helped my son's girlfriend a ton since they literally have no floor space for a tent. There's a lot of great people on here that can help with diet. Even if you have limited funds, your gliders are going to need more than just fruits & Veg though. You are going to need to supplement their vitamins, protein, calcium, etc. Look at some of the diets on Gliderpedia. No judgement just advice.
