She used to have a big appetite when she was younger, but as she got older, she seemed less interested in food. About two weeks ago, she developed wry neck, so I gave her niacin Since then, I noticed that she has barely been eating her food every day, although she has been drinking water well. To help, I started giving her vitamins through her water. However, I am confused by what happened to her yesterday her health declined very quickly and sadly she passed shortly after this post and I've never experienced anything like this before.
