You cannot mouseproof your dwellings if your cats are allowed to go in and
out by a cat door, or like mine, have a slightly open back door 24/7.
The cats will catch a mouse outside and bring it in for their meowmie's
delectation.  Sometimes they can't resist eating most of it and just leave a
head as a token offering.
I've stepped on a mouse's head on the kitchen carpet when I got up in the
morning more than once.  I have found the kitchen full of feathers too on
even more occasions, and a collared dove half eaten on the rug in front of
the fire.  That's Kitty FC.  She likes to eat those more than anything.  She
will always finish it all up.  In one way I don't like her to catch birds,
but in another way if she eats them and doesn't just kill them and leave
them, it seems better.
She will particularly do this if she disapproves of the latest flavour tin
of food I got her.
Someone's else's cat learned from her emails, if I remember correctly, was
it Adrian's cat, Bagheera?  I think so.
In America, I understand collared doves have to be purchased as they aren't
a native species there.  My friend Bob has one, he calls his Howard.  He was
a rescue as almost all his animals are.   The man is soft about animals  See
how stupid he is about them at:

There are so many wild CD's here I could almost fall over them.  They come
to steal the poultry food.

Refuse to eat the mouse's head, I don't think you'll like it, Helen.
