During the past two decades an increasing number of pet owners have chosen to take out insurance to cover the cost of veterinary treatment. Around 15% of the nation's pets are covered by insurance. There are a number of different companies in the pet insurance market. The largest in the UK has more than 400,000 policy holders, receives an average of 1,000 claims a day and every week pays out over half a million pounds to settle claims. It is not just valuable pedigree animals that are insured. There are policies for ordinary cats and dogs, as well as horses and other common pets like rabbits.
