It's the ultimate test of nature versus nurture - will a kitten raised by a dog, bark or meow?
Within a few weeks Trudy Collett will know the answer when her five-year-old Chihuahua Mischka weans her latest baby, a tiny black kitten.
So strong was Mischka's mothering instinct that she was happy to take on any baby, even a kitten.
The five-year-old came into season and began producing milk at the same time as an abandoned two-week-old kitten arrived in the Collett home.
From the moment Mischka saw the kitten, it was love at first sight; for the yet-to-be-named kitten it was the answer to an orphan's prayer - a warm bed and an endless supply of milk.
