We had four cats, two were sisters Millie and Meg, and when Millie died, Meg sat in a corner, and wouldn't eat for days.
She is great now, a new Siamese to play with.
Pete the Vet is a Vet in Bray, Dublin (but is Scottish) does a lot of media work. He said once that Humans would be arrogant to assume that other animals don't have the same emotions as we do. https://www.petethevet.com
