Based on your photo the cat shows no muscular definition. Again, small paws. Big &T^%R whatever it is. Critters in the wild are built to survive. This one looks like it has an account at Tim Horton's. As I wrote earlier I have a mounted lynx and when I compare it with your photo, nothing makes sense. Big cat, yes. Tiny paws. Your photo, hips are not pronounced or elevated.
One of my "outlaws" brought over 2 cats when she stayed at our home while we were going to PEI. Cats were giant, almost, no, ^%$%^^& scary. We had to put our cat in a kennel before they ate her.
Like I said, say "Here kitty kitty" and let all know who is prowling around your house.
