We purchased this 4 step Tree for one of our cats who has 3 legs.We ordered it on Wed., it came on Friday, & we put it together in no time at all today. It is just top quality, made beautifully & looks very nice. It fits perfectly in front of our bay window & she'll be going up & down to get up to the bay in no time after she looks at it awhile.Our other 3 cats are curious about it too.We can't believe the reasonable price, the free shipping, the 2 day delivery, & the high quality! We know now where to shop! Thank You!!
