My Aunt had a big cat. He weighed 30 pounds.
Mom always said that whenever someone would come by the house to see her and/or Dad, they’d hit the skids when they saw how big Casey was - they thought he was a bobcat. Then they pointed to his tail, which as as long as he was. I think he topped out at 41”, nose to tail. BIG cat, and they took him in as a stray kitten.
