Hello, my cat started to lose some hair ( a lot actually) on her back legs and thighs, and in a few spots close to her ears.
She is 11 years old, has been overweight most of her life but I limited her food intake significantly two-three months ago and now she is back to normal weight.
She is playful and acting normally. Jumping up to 4 feet high in the air ( couple feet higher then before) and stuff.
We also have a toddler who has been harassing her for awhile, now learning to treat her properly.
Can this be caused by stress/diet changes or we are in a bigger problem/ What to do? Thank you

It is likely diet related. Stop all dry food, feed either canned or fresh meat, and add 1/2 tsp of fish oil to the food daily. Also check for fleas.
