I am no expert, but if she is still under the weather tomorrow, not eating/drinking etc., then maybe a visit to the vet is in order. Having said that, my Peanut is ultra sensitive and can be an emotional wreck sometimes. Something can set her off and she will not eat, will not do anything but curl up and shake and act like the world is ending. Later that day or the next morning, she is fine.
Think maybe she is holding out for something better? She goes to her food, and sniffs it, but won't touch it. I've been raw feeding for almost a week now. This is the first time she's acted like this about food.
Could be--I just don't know. Some of the folks here are really, really good at helping out. My concern would be if she doesn't eat for 24 hours. But she seems like she's attempting to eat. I know Peanut will get that way--usually she devours food, and then she just won't touch it. The same food, same bowl, same location.
