Hi Bluey and welcome to pet talk! So sorry to hear about the occurrences with Mushroom! This could be a potententially bad situation and I'm with Margaret in that you might want to try and keep Mushroom inside for awhile. Of course, I'm biased and prefer indoor cat life, but with her getting injured it might in her best interest. At least until she heals. It sounds like she's encountering other cats (or possibly wild animals) that are fighting over their territory. Is she fixed?
