Which is more durable for cubes and tunnels - Fleece/fleece

[thinking]

or fleece/cotton?

I'm making a bunch and want to make the combo that will support them the best and hopefully last the longest. Approx. how long will they last before being chewed anyway?

Depends on the rats, some are more chewers than others. I personally like fleece/fleece especially for winter and fleece/cotton/or flannel for summer time.

I find things that are fleece/fleece tend to strech out a lot, hile ones that have flannel or cotton dont because its not a strechy fabric.

That is exactly what I'm finding as I struggle with my sewing skills today! I cut out a ton of fleece for things last night, but after sewing a few things today I'm starting to cut out flannel pieces. Guess I'll have twice as many as I planned on
