As one of its daily deals, That Daily Deal offers the Sly Dog Bottle Buddies 2-Pack in Rat, Parrot, or Cat for $4.99 with free shipping. That's tied with our July mention, $15 off list, and the lowest total price we could find. These re-purposed water bottles make a crinkling noise and measure 11". A style is selected at random. Deal ends today.
Of note, you can buy four for $6.98 with free shipping.
