12 year old Splash

Question
Recently my cat Splash" is going through some changes.
Weight loss-but loves to eat!

Loss of fur and very dry, now there is dandruff.

She is very lame due to arthritis, she is given a baby aspirin Sun and Wed.

Stays in a room upstairs most of the time.

Still likes to come for a visit when we go to bed and sometimes will stay the nite(she jumps onto the bed)

I love her so much just very concerned about the hair loss and dry skin. Old age?

Answer
Just like humans, cats over age 7 are more likely to get diseases as they age. Your description means that she could have anything from tapeworm to kidney disease. (in other words, without a visit to the vet, you don't know whether it is something simple or more serious)

If it were my cat, I would take her to the vet *immediately*
for a full checkup and blood work.

(as a checkpoint, cats around 15 yrs of age are relatively equivalent to a human who is about 80 yrs old)

Thanks for the question.
