We have been trialing Pet Remedy diffuser on our rescued Parrots, many have long term self mutilation issues by the time they get to us & we have found that Pet Remedy has helped a great deal in calming them, we’ve also found it has reduced self mutilation in some birds & has also created a much calmer atmosphere & reduced the squabbles between them. We will definately be continuing to use this great product & would recommend it for anyone who has a parrot.
