Please help. My son's tarantula is a Mexican blonde. It was captured in the wild and we have had her for about a year. She's molted a couple of times with the last time being two weeks ago, almost to the day. This morning she was on her back and very still. She would move around periodically and had fluid coming from her fangs. I figured she was molting, again, but have been worried since it has been such a short time since her last molt. I've kept a close eye on her and suddenly she was up and around, again, but did NOT molt. Now she is very agitated. She is acting odd, almost stamping her legs in place, slingling dirt. She almost seems like her legs are stuck. Sort of off-balance. Also, she has a small amount of webbing on her backside. I'm scared she's sick. Please help if you know what might be happening. Thx.
