Prestige Cat Trees XXL Heavy Duty Cat Tree is the purrfect choice for all of the large breed cats out there. What makes this design unique is the 18" round circular perches that can comfortably accommodate the largest of household cats and of course provide a little extra space for those two cats that just like to cuddle. These perches are 19" wide at the exterior and 17.5 measured by the interior and also have a lip to keep kitty secure and safe inside the perches as they sleep the night away. They are staggered from one level to another allowing easy access for those less agile cats. Proudly designed and built in the USA with quality materials such as wood, household carpet and thick natural sisal rope. If you are looking for a cat tree that your BIG cat can enjoy, look no further as this is the one.
