What to do with an unidentified bug?
I have found a bug on my rug near the cat and was wondering wat kind of bug could it be and if it was dangerous.After awhile of searching on the internet I found nothing. The bug is brown with 4 long legs atretching downwards of its body, also it Bug resembles a tick slightly but isn't flat on any side. It seemed to have another 2 extremeties that looked like arms. it seemed chuby or filled with soem kind of liquid like a tick after feeding and has 2 very long antennas. Also it seems to be a mix of a tick and some kind of roach.
