My calico kitty is 14 years old. This year she passed her vet check as fine, regardless some weight loss. She was always overweight so I keep worrying something is up with her. What is most visually concerning is that her front paw pads (foot) are looking longer and longer when she walks toward me, almost like her foot to "elbow" is flattening. Her paws are unusually large but I cannot determine if she always had them or not, since she was always a fluffy longhair kitty. I am just worried something is going on but not sure. She is very gentle and loving, still runs and plays (though less than usual, she avoids running up her cat tree lately), and spends her time on my lap or sleeping. Could this be arthritis? She has a kinky tail since birth and always had a funny walk, with her hind legs kind of separated wide. She doesn't let me touch her paws but again, she never did. Could her weight loss be causing some issues? Thanks in advance!
