Don't feel lonesome, hugoawens, I've been on this forum for many years and I don't know who Gella is.
Caution on these fleece tubes and hammocks. Remember, chinchillas chew on everything they can get their little teeth into, they will surely do so on the fleece tube, in addition to urinating in/on them and pooping in an on them ... Fleece is washable, but it also is known to shrink. Between the needing to be washed and the chin's chewing, I don't think they would last long. The dye in the fabric is also another question that might concern me.
A tube tunnel made of white PVC pipe is more durable, will last longer and is easily washed.
As a matter of fact, that tube tunnel in the picture looks like a PVC pipe covered with fleece.
Always remember: Those things that are manufactured for animals, are often not manufactured with the animals in mind, but with what might seem the most pleasing to the eye of the human that purchases them $$$ regardless what the consequences may be to the animal.
The fleece tunnel tube I want ...
Chinchillas are very happy with a 5 or 6-sided hut made of pine, a lookout 4-sided box made of wood attached to the inside top of the cage, a tube made of PVC pipe as a lookout attached to the top of the cage, and/or a "Y" or "T" shaped 4 to 6" diameter PVC pipe placed on the bottom floor to play on and sleep in. Handmade wood chew sticks.
Not only do the chins enjoy it as much as the expensive stuff, but just think of the money you could put in your chinchilla bank in case of an emergency.
