In response, the supermarket chain has quadrupled its Christmas gifts range for pets from 12 items last year to more than 50 this year.
Treats include Prosecco and beer for cats and dogs. The tipples (called Pawsecco and Bottom Sniffer beer) go on sale this week.
Tesco pet food and accessories range manager Fiona Moss said: “Britain has always been famous as a nation of animal lovers. But now more and more cats and dogs are joining the festive feast with their owners.
“In the past, lucky pets could look forward to leftovers from the Christmas dinner table. But now many people give their cat or dog a special festive meal in their own right.
“Last year our posh Christmas dinner for cats – a special turkey and sage meal – became our most popular festive item for pets.
“This year pet owners can even go one better, for while we’re all enjoying a glass of fizz or a beer at the festive dinner table, our cats and dogs will, for the first time, be able to join in the toasting too.”
Pawsecco is a non-alcoholic, non-carbonated grape-free ‘wine’ drink containing a blend of elderflower, nettle, ginseng and limeflower.
Bottom Sniffer beer is made from flax, dandelion, burdock and nettle and is designed to create a feeling of well-being.
Both drinks, which have been created with the aid of veterinarians, go on sale at Tesco stores across the UK today (Wednesday November 29), retailing at £3 a bottle.
Other gifts include an advent calendar for dogs, Christmas crackers for both cats and dogs, and treat-filled stockings.
Foodie presents for dogs include Christmas dinner turkey pate with sage and carrots, plus Christmas pudding biscuits.
