Rats. <3 Seriously. I had 3 generations of hamsters, and I fostered some mice, guinea pigs and a bunny for a local "exotic" pet rescue before I chose to adopt some rats. There were no rats in the rescue at that time, but I told the rescue that I was very interested in adopting some if they came in. A few weeks later, an accidental litter of rats was born in the exotic vet that one of the founders worked in, and I was able to pick out two little beige boys! Some of the siblings were adopted by vets. xD<br /> <br /> <img width="350" src="http://i255.photobucket.com/albums/hh152/Saeko-san/Pets/TuckandCaelPlay2.jpg"><br /> <img width="350" src="http://i255.photobucket.com/albums/hh152/Saeko-san/Pets/TuckerComing1.jpg"><br /> <br /> I can't photography to save my life. :x<br /> <br /> Tucker and Caelum were just fantastic. Rats are by far the best rodent pet I've owned. They're quite the troublemakers, though, they get into everything. The could scale the vertical side of my bookshelf. Not to mention fit under every single piece of furniture that ever existed. They would rather climb on me, though. ^^ We used to build tunnels out of my covers.<br /> <br /> Unfortunately, both of them have passed away. :c I found a nasty tumor growing on Cael's leg, and the vet (same place I adopted him from) told me it was probably sarcoma, and it was growing around the bone. Amazingly, they were able to operate and remove all of it. Seriously, it's completely worth finding a competent small animal vet near you - that extended his lifespan by a month or so. He was a cute, little 3-legged rat. x3 Unfortunately, his cancer had metastasized, and lung cancer took him not long after.<br /> <br /> As far as hammocks go, Shadow, you can see the hammock in that second picture - Tucker and Caelum loved it for a year or so. :) I moved it around the cage every once in a while. They used to sleep in it together, all snuggled up. However, once Caelum passed away, Tucker... kind of tore the entire hammock to pieces. :( <br /> <br /> They used to love the toilet paper tubes. They'd chew them up and decorate with the pieces. You could try hanging a toy from the top of the cage to see if they like it? I think I did that, but they weren't very interested.<br /> <br /> Also, I was going to recommend <a href="http://www.martinscages.com/products/cages/rat/">Martins Cages</a>, but I see you have one already... which actually might be from that place? xD Looks similar.<br /> <br /> Sorry for the wall of text. :x Have another rat picture.<br /> <br /> <img width="350" src="http://i255.photobucket.com/albums/hh152/Saeko-san/Pets/CaelumPeaking1.jpg">
