Sounds like you're a bit of an animal lover doglet.
We have a dog we rescued from the pound and a galah we picked up from the side of the road, have also cared for a baby wombat, echidna, kangaroo, kookaburra, cockatoo and even had a wedge tailed eagle for a couple of days.
I refer to my neighbour as "the mad cat lady" as she has now domesticated 3 feral kittens and they spend more time at my place than hers!!
Can you post a picture of the greedy crow in action ?
would love to see it.
