Got this for my cat’s birthday and it was a hit. The meow sound started as soon as she opened it and kept playing for over three hours. My dog was confused at first, then just started barking at it. Definitely a fun surprise.

The card looks cute and the sound is exactly what I expected — a playful cat meow loop. It’s a great prank for cat lovers. The only downside is the sound gets a bit annoying after a while.

Perfect for a cat owner’s birthday. The card is well-made and the sound is realistic. My friend opened it and couldn’t stop laughing. It’s a unique and memorable gift.
