It just depends I guess.

Last Christmas I was wanting a cat, I did all the research for the care and ect. After I tolded my mom how much I wanted a cat, her and my dad got me one. And they got me the perfect kitten! Maggie! But you have to be careful getting a pet for someone because their personalities might not match. But I like idea of getting a certificate so you can let them find one they like.
Good Luck
