It was the large option at the time but it is not as large as the one in your link. Mine is also all grey. I got 2 cats from my local animal shelter, they were about 2 and 3 months old at the time and the younger one was a little bigger than the older which should have been a warning sign. They are both American shorthairs. My older cat is white with a calico saddle and is only a little bigger than average, she is 14 lbs. My younger cat is almost solid black with 2 little white toes on one of his back feet. He is 22 lbs, over a foot tall, and from his nose to the end of his tail he is 39inches. He can stand on his back feet and get stuff off the kitchen counter.
