British supermarkets are warning of a shortage of several dog and cat food product lines following a demand in pet ownership in lockdown.

Sainsburys, Morrisons, Waitrose and Tesco have all said that dog and cat food pouches are flying off the shelves and stocks are running low.

Sainsburys apologised to customers after running out of specific products due to a 'national shortage', and Morrisons said it might not have 'full availability for several months'.

Both supermarkets said the shortages are down to a higher than usual demand for pouches, with more pets being bought during lockdown.

A spokesperson for Morrisons told the BBC: "We're working closely with our suppliers who are investing in increasing their capacity and we may not have full availability for several months."

But the supermarket added that there was no need for people to start panic-buying pet food.

"We do have enough stock to support all our customers and their new pets and so there is no need for people to buy more than they need."

Pet food maker Purina also told the media outlet: "We are experiencing unprecedented demand for our products, including cat food pouches where we have seen sales growth for our Felix and Gourmet brands at almost three times that of the market.

"We have been working hard to meet this additional demand and are producing more pet food - including pouches - than ever before."
