I noticed today she (Cobalt tinc) was catching a fly, pulling it in, but before it got to her mouth sometimes she would look like she was gagging and then drag it a bit and drop it before trying to catch it again. Then she'd eat a couple with no problems, and then it would happen again. I tried to watch closely to see if there was maybe something stuck to her tongue but I didn't really see anything or couldn't anyway because she's so fast. Sometimes she would drop the same fly a couple of times before getting it. She also was a little less enthusiastic to get going this morning (not entirely... she still polished off at least 50) but a lot scattered on her this time. Does it sound like there is something wrong?
