PETS at Home is recalling four lines of dry cat food products after three cats became ill.

The store, which has shops based in Bolton, Bury and Prestwich, is recalling four lines of its AVA dry cat food products because there are lower levels of thiamine (Vitamin B1) than specified in the recipe.

The product being recalled is dried food or "kibble" designed for older cats and neutered cats kept indoors. The rest of the AVA range was safe to use, the company said. The AVA range is manufactured in the UK and sold exclusively at Pets at Home.

A spokesman for the Food Standards Agency said: “Your cat should not eat affected product batches.

“Thiamine deficiency in cats may impact a cat’s health. Three cats have so far been identified which became seriously unwell after switching to one of the affected products and exhibited symptoms ranging from sudden collapse, fitting, widespread twitching and general unsteadiness which are not the classic symptoms of thiamine deficiency.

“If you have bought any of the listed products with the specified product codes, please return it to where you bought it for a full refund or call 0800 328 4204.”
