Hi, thanks for using Petco Pet Education Center, formerly Petcoach! If the brown liquid was very smelly (like rotten eggs mixed with poop) then she likely expressed her anal glands. Anal glands are scent glands inside the anus that are expressed with defecation. If she was scared suddenly they can accidentally release the anal gland material. The other possibility is that she is starting with diarrhea and some leaked out. Keep an eye on the litter box and see how her stools are. If you see diarrhea then I would bring a sample to your Vet and have her seen. I hope this helps and I wish Luna Girl the best!
