"Don't Hate Cuz I Am Puurfect" Tee is great for fashionista kittehs such as Goma. It is available at Goma store right now! Goma is wearing size M, but I hoped I got L....it looks kind of tight on him. Sometimes I forget he has so much fluff!!! He is 13.5lb right now. If your kitteh is smaller than that then M is fine. I gonna make another t shirt again soon and have collections of them on Goma store!
