I have noticed over the last week or so that my cat seems skinnier than usual. She has always been a small cat, frame wise, and her weight has matched that. But lately she is more boney. It's not like she has lost a crazy amount of weight, but it's still noticeable. She is eating like normal, runs around, and snuggles. Is this something to be concerned about?

I will call the vet in the morning if need be, but I wanted to get some input from you all first.
