Hi! I am not to sure about that I will look into it but I would assume not only because it is scented and usually any odour reducers have chemical in to that are unsafe for your parrots . But I will see is the bird cage stinking or is it from another animal. If you have multiple birds it is common to have a scent of course but I should not be strong to the point where you can’t handle it. If you want to reduce door you can boil some water and but different fruits and spices in the boiling water to give the surrounding rooms a good scent that won’t harm your parrots. I can’t find anything about this particular brand but I would stay on the safe side and not use it just because most de-ordering products contain toxic chemicals not safe for animals.I bought this and I was wondering if it was harmful to birds? Lmk! Thank you!
