This knit and crochet cat shark hat is made with pewter gray acrylic yarn and white felt. This is the perfect gift for the crazy cat lady in your life or a cute photo prop for your own kitty. The hat measures 2 inches across from ear hole to ear hole and the ear holes are 2 1/2 inches wide. It has 8 inch long ties on each side and the hat has some stretch to it. This should fit an average size cat. My cat Jenna, which is pictured weighs about 8 pounds. If you need a larger size hat please send me a message. Machine wash and dry on delicate. Made in a smoke free home. Please allow up to 1 week for this item to be handmade for you. ***Please do not leave your cat unattended while wearing this hat. If you intend on using this cat hat for a special occasion or photos, please give your cat some time to get used to it. By the fourth time I put this on my cat she would leave it on. The first couple of times she tried to take it off rather quickly, now she's not bothered by it at all.
