Paws Inc. and Bare Tree Media have teamed up to release a set of 24 birthday cards featuring Garfield, in celebration of the character’s 39th anniversary.

The new cards will be sent in the form of a sealed envelope through a text message and will automatically open to surprise the recipient with a birthday message from Garfield.

The Garfield Animated Cards are now available for Apple iMessage or the “Garfield Sticker Tap” mobile app, which is available on the App Store and Google Play.
