Option 2:
Lots of players need special gear either for accessibility or other unique reasons.  Elly is no different. Being a literal big cat she is in need of a jersey that can suit her body and her fur. Her particular needs mean that sleeves are a hindrance. She has a jersey that goes down her back and can latch around her belly but on the arms and legs they are elastic bands that hold the jersey to her body as she moves around the ice. They stretch and don't get caught under her limbs in odd ways. Her back is prime real estate for the teams logo, but she also has the symbol of her home zoo and Sapporo near her shoulders. Lastly the jersey is a more synthetic type material to help prevent static build up so she doesn't accidentally shock other players or herself. She does have a small bit of head padding with holes for her ears (but also protective too). And a little moisturizer pad for her paw pads she carries in the locker room to make sure they aren't too raw after a full game set on the ice.
