Pets at Home has recalled four dry cat food products marketed under the AVA brand after three cats became seriously ill, four to six weeks after switching to the products.

Further investigation revealed that the products in question: AVA Mature Cat Chicken 2kg, AVA Mature Cat Chicken 4kg, AVA Senior Cat Chicken 2kg and AVA Adult Cat Neutered Indoor 1.5kg, all had insufficient levels of thiamine (vitamin B1), which caused the cats to exhibit symptoms of sudden collapse, fitting, widespread twitching and general unsteadiness.

Talking to the BBC, Pets at Home spokesperson Brian Hudspith said it was important to alert veterinary surgeons as well as customers because thiamine deficient cats would usually present with quite different symptoms, including stiff limbs and the head falling onto the sternum.

He said: "Rather than the more typical cervical ventroflexion (head falling onto the chest) associated with thiamine deficiency, in the three cases we saw the predominant clinical signs included sudden collapse, fitting, widespread twitching and general unsteadiness on their legs, which began suddenly after 4-6 weeks of being on the diet."

Pet owners who have bought the products are being advised by the company to dispose of the contents and return the packaging to any Pets at Home store for a full refund. Owners who think their cat is demonstrating any of the symptoms are being advised to seek immediate veterinary advice, and to contact the company's customer advisors on 0800 328 4204.
