The past 2 months my daughter and I have been getting these bites on us. When we get up in the morning we find bites on our back, shoulders, arms, legs and backsides. We are not sure what kind of bites these are but are really tired of them. We have a cat but she has not been scratching or biting and we have not seen any fleas. But we have seen these little tiny-like bugs that are very light tanish brown bug. It was about the size of maybe 2 or 3 mms long. I have never seen these kind before. Could you tell me if these are the culprit that have been biting us?

They could be bed bugs.

NivaZimel is possibly correct. Bedbugs that have not fed do have a light brown color.
