This was on my back door step when I let the cat in. He had only been out for about 10mins. I think its something he has vomited up!! He is absolutely fine in himself, the only thing I've noticed since finding this is his meow has gone a bit croaky.
He is up to date with worming.
He does eat mice and is a relentless hunter, maybe a mouse that hes tried to eat then threw up? It just looks really strange, anyone seen anything like this before? Sorry for the gross photo!!
