Where can you get a tabby cat from?

From a rescue shelter -- where all the best pets can be adopted into new forever homes.

Another Answer:
I rescued my cat from the streets.

My partner and I were walking when this boy, possibly no older than ten years old, approached us with a little kitten stuffed inside his hoodie/jacket. Naturally I went "awwww! Lookit the kitten!", then the boy offered to sell us the kitten for just £10. The boy seemed desperate to get rid of the kitten, and was headed for some big indutustrial-sized trash cans when we bumped into him. If we hadn't have taken the kitten, he would have ended up in one of those trash cans, or worse.

This tiny kitten was no older than eight weeks old when he was rescued. He is now just over a year old and is glowing in health and life.

If you are looking for a pet cat, then I fully agree with the first answer. There are thousands of cats that are waiting to have loving forever homes in shelters.
