Help I've got mice in kitchen they got into dog and cat food bags under kitchen sink. Been cleaning since 5.30am ?
Store the cat and dog food somewhere else. If, as I suspect, it is dried food put it in airtight tins.
Next have a serious conversation with dog and cat - it is their job to get rid of mice, not yours!
Close both the aforementioned pets into the kitchen with you while you clear out that cupboard, hopefully cat will enjoy a good old-fashioned mouse hunt.
Scrub cupboard thoroughly then inspect it carefully to find out where the mice are getting in. This will entail the use of a strong torch or lamp and may well entail emptying all the adjacent cupboards until you find the hole or crack.
A crack the size of an ordinary pencil is large enough for an adult mouse to get in and out of!
Block hole or crack with polyfilla, if you should happen to have any wire-mesh lying around, place it over the crack/hole before applying polyfilla or plaster. Ground up glass in the plaster or polyfilla deters the little beasties too, but do remember if you use glass not to smooth the polyfilla with your hands!
Leave cupboard open at night for the next week or two and insist that cat sleeps in kitchen!
If after all this bother, you still have mice, buy a mouse-trap or a new cat who likes catching mice!
Good luck - they are right little bu'''''s to get rid of!
