Ours likes to bring in moths and flies and other creepy crawlies she finds at night. Some days we come downstairs to find bits of moth scattered over the front room!
Years ago a previous cat of ours was sat on the front step eating something. Upon closer inspection it was a fish. Unfortunately it looked like a fish that belonged to a neighbour who took great pride in their fish pond. Turns out that particular fish was missed as it was rather expensive![]()
You have a mouse infestation.
Your cat is catching the mice.
I fail utterly to see the problem.
That is literally the spitting image of the mouse I just fed my snake... albeit that mouse was already dead!
