How to match information between tabs?

Question

How can I take information from one tab and add it to another?

For example, I have Tab 1 with column A - call it cat breeds - and I have Tab 2 with column A - call it cat breeds as well. They need to match so if these two match I need Tab 2 column B with cat names to show in Tab 1 on the same row that matches the cat breeds in a new column.

Answer 1

I'll have a guess that:

=vlookup(A2,Tab2!A:B,2,0)  

in Tab1 B1 and copied down might suit.
