Whisker + Box...the discerning cat's answer to the cardboard box! Your furry feline (or small canine friend) will spend hours happily squeezed into this mod box and will look great doing so!The Whisker+Box design is based on the veterinary science of compression therapy which translates to a sense of calm and security for your pet. While it may look "too small" for your big cat, it's all about the SQUEEZE.   HAVE A LARGER CAT? You asked for it, you got it!  The gorgeous Penelope insisted on squeezing her 26 lb physique into the original Whisker+Box.  We’ve now added 2 inches in every direction the the original Whisker+Box for our larger feline friends 20 lbs and up. Currently available in Turquoise only. We still recommend the original size for cats in the mid-teen pound range as it’s really ALL ABOUT THE SQUEEZE!   Switch out the tattered shoe boxes sitting on the living room floor with a clean, modern object to complement your home, veterinary practice, shelter or cat cafe. Also ideal for foster cats since this box promotes calm, security, and can also be disinfected.
