My cat is 17 years old, under 4 pounds and tends to fall off tables, counters, etc., or just falls over while walking occasionally but after a couple minutes gets up and seems okay. It seems that every day there's a moment where she falls over, tries to get up, chills around for a little bit, not sure why, but then she always walks away like nothing happened. Any idea on what to do to make her stronger or is it her time?
