Have you always wanted a pet cat and a bird, but you only had enough money for one of them. Well, I have a solution. Just follow the steps below and you will have a cat and a bird in no time.

1. Buy a cat from the pet shop or wherever cats are sold.
2. Setup a place birds would like to go in your backyard with food for them.
3. Let your cat go outside whenever it wants to. It will start looking for a bird for you.
4. After a month or more your cat should have got a bird for you and will bring it inside.
5. You now have a cat and bird, but you only bought the cat. 

And there you have it, you now have a pet cat and bird.

Note: it may take a while for step 4 to happen

I hope this helped.
