UK supermarkets have warned of a shortage of pet food pouches in 2021 due to a rise in the number of people buying pets during lockdown.

On March 9, Sainsbury’s had to apologise after running out of dog and cat food pouches, although tinned and dry food was still available.

So, what brands are affected, will shops run out and what else could you feed your pet if you can’t get their favourite food?

Why is there a pet food shortage?

Sainsbury’s claimed a rise in pets purchased throughout the coronavirus pandemic has led to the shortage.

In an email to customers, the company said: "Due to a national shortage of dog and cat food pouches, we're sorry if you're not able to find your usual product at Sainsbury's.

"We're working hard to resolve this. We think the issue will be ongoing through the year, but we hope to get them back onto shelves as quickly as possible."

In January, data revealed that 1,800 people called the Dog's Trust over in the last three months of 2020, all looking to give up dogs under the age of one.

The Kennel Club, the largest organisation in the UK devoted to dog health, welfare and training, claimed a quarter of new puppy owners had impulsively bought a pet during the pandemic, without research into their needs.

It appears that the sudden rise in people taking home puppies and kittens has had an impact on the availability of pet food, with suppliers unable to meet demand.

Which brands and types of pet food are affected?

Sainsbury’s stocks leading brands such as Sheba, Whiskas, Felix, Cesar and Pedigree. It is not known if specific brands are experiencing more shortages than others.

The supermarket does still have a variety of brands in stock, of both wet and dry food.

The shortage affects both dog and cat food, but it is not known whether it affects food supplies for other types of pets.

The supermarket has now warned "some products might become unavailable".

Competing supermarkets are also thought to be affected by the shortage, including Tesco.

It is not thought that the shortage has been caused by panic-buying, which caused a similar shortage of pet food in the first half of 2020.

ASDA and Morrisons have not made statements on whether their pet supplies are running low.
