I bought 1 of each size to test them out. The shortest bridge is very small! I think the medium one is best for acting as a way for a hamster to climb on top of a hut or dwelling. For that reason, you should take out some measuring tape to see how far each of the bridges would go. I would probably only buy medium-length ones. Maybe a short one if I was using it between 2 close hideouts. Note that the wavy bridges have little joiner shapes at one end to connect either to Niteangel hideouts or generic joiners to connect to other brands' hideouts. I found I could rest the ends of the wavy bridges on hideouts that weren't from Niteangel and it worked fine, although the fit obviously wasn't as good as it would be with Niteangel hides.
Here's the thing... my Syrian would not walk on them unless they were flat against the ground.
He would sort of look at one and put a foot on it but then he'd go around or try to pull himself up without walking on the bridge. He would not use them.I was going to see if I could replace my generic bendy arch bridges (see below) because I read about the dangers of the gaps in bendy bridges if you use them as barriers (A Word of Caution on Bendy Bridges). I figured even though the gaps are more dangerous if you have the bendy bridges set up as fences, maybe the gaps are still dangerous when used as bridges?
So I bought the Niteangel bridges and put them around his enclosure. In one case, I replaced a narrow bendy bridge in my hamster's sand bath. What did he do? He jumped into his sand bath and after he was done he pulled himself out with some effort. He investigated the Niteangel wavy bridge (medium-sized in this case) but would not walk up it.
I'm trying to think about why my Syrian wouldn't use them. Is it because the gaps between the steps aren't big enough for his feet and nails? Or is it just his personality and he didn't like the texture of them? He would readily use the generic bendy arches that are around.
Unfortunately, I don't have a dwarf right now to test them on. I feel a dwarf would walk on them okay, considering that all their pictures are of a dwarf on the wavy bridges.
Has anyone else bought the Nitangel wavy bridges? What do you think? Have your hamsters used them? Would your Syrians use them?
Niteangel wavy ladder bridges. Generic bendy arch bridges.
A Word of Caution on Bendy Bridges
"Bendy bridges, as the name suggests, are intended to be used as bridges and not barriers. When used on their side as a barrier, they create what is essentially a guillotine for tiny paws & limbs and there have been several instances where hamsters have got legs caught, resulting in severe injury (broken and even amputated limbs) and even death. What happens is that when your hamster climbs over them, they can push their paws down these gaps & due to how narrow the gaps often are, their paws can become pinched and trapped.
I understand they are more aesthetically pleasing than a piece of cardboard or even plain wood, but they are a potential death trap in your hamsters enclosure. If you wish to use bendy bridges as barriers, you MUST secure the gaps with silicone/glue, moss, or even glue rocks onto the edge of them so your hamsters paws can’t slip through the gap. - however, you must overlay the rocks or they will also create pinching gaps that can entrap tiny paws."
