Cats just love to swat at bubbles, but it's a very short game, because the bubbles usually pop immediately when kitty touches them. Crazy Cat Catch-A-Bubbles are not your average, run-of-the-mill soap suds. They are made with a special non-toxic formula that results in iridescent bubbles that are much more durable. So kitty can have more fun chasing them down and smacking them around.
