I was worried about potential chewing, and ingestion of the fibers too especially after watching someone's homemade one on YouTube get chewed. AND of course I was thinking it is NOT a great idea for Squirt to get hormonal when I really don't like being bitten :P
Cropoliths are such a danger, that I won't even put coconut fiber or jute etc. in with any my birds because they have also known to cause cropoliths.
The cold is a big issue here, but I have time to prep now ... in winter it will get up to MINUS 10 C ... so I run heating for the birds too - but I love the look of the heater so thank you Anya. That is something I will order! I have heated puppy pads to go under but I like the look of the birds snugglers better!
