Following the launch of Pro Plan Liveclear, the Purina Institute is hosting a two-hour CPD symposium on managing cat allergens which will take place online on Wednesday, 8th July at 7:30pm. 

Speakers at the free event will include feline expert Dr Andy Sparkes, BVetMed, PhD, DipECVIM, MANZCVS, MRCVS and the immunologist who led the Purina research behind Liveclear, Dr Ebenezer Satyaraj, PhD.

Andy will address the consequences of feline allergy. He says that in majority of cases, cat-allergic owners will choose to tolerate ongoing symptoms of allergy, rather than relinquish their cats, even when they have severe symptoms.

Ebenezer will talk about the research behind Pro Plan Liveclear and how it will allow veterinary surgeons and nurses to help support these clients.

Libby Sheridan, MVB MRCVS, Purina Veterinary Technical Affairs Manager, UK & Ireland said: "This innovation is safe for cats who continue to produce the major cat allergen, Fel d 1, which is found mainly in the cat's saliva and sebaceous glands.

"Our researchers found that the Fel d 1 protein could be neutralised through feeding a nutritious cat food coated with an innovative egg product ingredient containing anti-Fel d 1 antibodies1 which helps reduce the active allergen transferred to hair and dander during grooming, and ultimately helps reduce active Fel d 1 in the environment.2

"Now the science has resulted in a commercially available product that could have a big impact on the quality of life of the cat and their owner. We'll be sharing the research behind this at the symposium so that clinicians can evaluate the potential benefits."

Any member of the practice team can register for the event at, and will be entered into a prize draw to win an iPad. There will also be a number of goody bags available as additional prizes.
