I have a small concrete fenced in back yard area and want to set up a hammock. Anyone know of some hammock stands that take up minimal space, or does anyone have an opinion of what hammock is most comfortable. Rope, Quilted, Parachute, etc... Thanks

My rats are getting lazy and bored alot lately. I have 2 sets of rats. My boys, they are both around 5 months old. And my girls. One is probly about 3 months old. The other, only 2 months at the most. The males and females are in different cages of course. Iv tried my best to give them fun things but it seems like there all the same. I make hammocks and nets and stuff like that for them. I had a glass jar in with the girls and they loved it but it got dirty fast and I couldnt clean it properly so I had to get rid of it. Currently in the girls cage there are, 2 small tube hammocks (the older one likes a hammock to herself), A plastic hut (they dont like it), A lava rock perch. And a braided rope with a bell on the end. In the boys cage there is, a large tube hammock, A large full level hammock on the top, a small hammock made of net, 2 wooden stick perches going across the cage, and a lava rock perch. My boys are getting older and there not doing much anymore. They dont like ropes. But they love to climb. The girls injoy chew toys but I find they go threw them in minutes. Does anyone have any ideas. Maybe some cool designs for hammocks. Or homemade chew toys? I dont have alot of money so I prefer to make them myself. Thanks. Please don't link me to Dapper Rat. I already know that site like the back of my hand. Thanks.
