A big THANK YOU to Dr Phil Sacks and his staff for removing obstructing life threatening fibres from a much loved cockatiel. This procedure had to be done due to fibrous perches and toys inside the birds enclosure. 'Goku' became so fond of them that he decided to ingest them....A few days on he developed a huge lump in his chest.He lost a lot of weight because the fibres were obstructing any food that tried to make it's way through the digestive system. I asked Dr. Phil why these products are on our shelves when they can do so much harm? His reply: Why do we buy chocolate when it is so bad for our teeth or why don't we exercise more when it is so good for us? Anyway, I got the drift.This is my plead to all those caring bird lovers : PLEASE avoid products with fibres for your beloved companions. Not only was it a costly (but worthy ) procedure but the animal suffers .I know that many of us are not aware of these things and we think that we are doing our animals favours by providing them with these products. In this case not so . Now from experience I will stay well away from perches with fibres!!! Thanks to Dr. PHIL 'Goku' is all well and is making up for all those undigested treats. In other words he gets spoiled you wouldn't believe. Thumbs up for the 'Burwood Animal and Bird Hospital'.
