Groomer cut my cats nails too short?

MsD💋

I didn’t notice until he started trying to open the door in my room when he got home from the groomer and there was blood on the door and I got a quick look at his nails and they were bleeding and cut way too short.

He doesn’t seem like he’s in any pain and he was attempting to use his scratching post like normal but I’m still concerned because this never happened to him or any of the other pets I had. Will he be okay? He’s not bleeding anymore I don’t think.
