A friend of mine has some kind of parrot and a cockatiel+5 cats,3 of them Siamese. The bird-cages are always open,but they are hanging from the ceiling and my friend has constructed all kinds of branches and things for the birds,so much fun to watch....The only cat that is really interested is his 2-year old Siamese,always trying to get to the birds and although he is incredibly agile he could not jump that high....the other cats don't bother..
But of course you can never be sure....
Here are the two birds and the other pic is the Siamese culprit"Junior" and "BiBi"whom I would steal if I could,he's a wonderful cat!
