I have a short haired cat , he likes to sit on the couch with me , but lately I have been feeling little ticklely feeling on my skin, what is it?

Are you allergic?
Is there too much cat hair on the couch?
Does he have fleas?
Do you have dry skin?

Our bodies can change. You may have developed an allergy. Or of course fleas are possible, or has cat gotten into some substance ?
