Hello, I really need help to identify this tiny bug. I've been getting random bites on and off when asleep for the past few weeks. We have a cat so I have been worried it is flea bites, or worse, bed bugs. We sleep with the window open but I haven't heard any mosquitoes buzzing around. All late night searching efforts have proven fruitless until last night when we spotted this tiny bug walking across the pillow. Can you please tell me what it is? It's back body appears to be full of blood. Thank you!
