Poor Tosca, Christmas causes so much disruption. Everywhere she goes, someone says she is in the way. Where is a poor kitty to nap? Eventually Tosca causes an accident and gets exiled to the snowy outdoors.
I picked this up because my library system doesn't have Mog's Christmas. As far as I can tell from the description of that the story is pretty much the same, but the style of illustration is very different.
Both author and illustrator clearly love and know cats, so I think this will appeal most to those with their own feline companions.
