My Cat Named 'Cat'

When we first got 'Cat', she was very calm, timid and skinny, but still very friendly and affectionate.
Then came the first night........
I woke up at 5 A.M from hearing a BANG! I looked over and across the way was 'Cat' on top of my bird's cage, tryihg to get in. I got up and told her to get down off it and she did.
No hope left........this has now become a regular thing for 'Cat' and you'd think it may be cruel to the birds when you first hear it, but when she's not around the birds get angry! Pretty messed up, huh?
Other strange things that 'Cat' loves to do is chase air.....
Yes, that's right. She has all the toys any cat could ask for but instead, she hysterically runs around the house with an imaginary friend and takes imaginary baths.
