Hi everyone! I’m going to be a first time rat mom in about 2 weeks and I’m starting to make some hammocks for their cage, but accidentally got flannel instead of fleece. I read that flannel isn’t as good as fleece because it is %100 cotton and produces threads, but is it possible to use it as the bottom of the hammock? I went back out and bought some blizzard fleece to make the top out of (the part they will actually lie in) but can I still use the flannel as an absorbent under layer or will they get into that? Also, I have 3 of those bendy ropes for parrots; do these get soiled/are they cleanable? Should I make a slip cover for them to swap out and wash to prolong their life or just leave them as is? Thanks!
