Thank you! I will try to find an unscented detergent like Halo here in the US. I double rinsed the fleece and did not put a dryer sheet in, but we are holding off putting it back in as our Chinchilla is very ill. We have been removing elements to see what helps. He is on antibiotics, Critical Care, Bene Bac and gas drops. We just can't kick the sneezing.
A little history: We got him & a girl. Girl was in respiratory distress at the store. She died w/i 2 days. He has a level 3 heart murmur. This is his 3rd week on Enrofloxacin (generic for Baytril). I'm concerned 1 - loss of cage mate & 2 - is it the cage (Critter Nation 162) &/or wood hutches & shelves (husband made from Poplar).
