Cat owners warned
Meanwhile animal charity Blue Cross has warned pet owners to keep cats indoors, away from gritter salt and antifreeze which can kill them.
Chief vet Mark Bossley said: "Salt is poisonous to cats and it can easily get on their paws or fur and be swallowed when they groom themselves.
"Watch out for antifreeze too, cats seem to like the taste but it is highly toxic to them."

Elsewhere, Italy's having its coldest week for 27 years.
Around 11,000 people are trapped by snow in remote villages in Serbia.
