I have a friend whose dog is celebrating his birthday this month, and I'm having a heck of a time finding a card to suit the occasion. I've seriously scoured the greeting card section in all of the shops within a mile radius of my apartment, but none fit for a puppy's second birthday. Fancy that, right? Thankfully, I found Sincerely, Fido who specialize in greeting cards just for pets. From welcoming a new kitty into your home to graduation cards when your best pal's pup finishes obedience school, they've got almost everything in between. You can even find cards from animals to animals . . . with your choosing help, of course. Although they can't be found in stores (yet), with a bit of advance planning, you can pick 'em up online!
