All cats produce the Fel d 1 allergen in their saliva, which is then transferred into the home and onto their fur as they clean themselves.
In the first 3 weeks of feeding PRO PLAN LIVECLEAR, the key protein source from eggs safely binds to the Fel d 1 allergen and starts to neutralise it. As every cat is different, the level of Fel d 1 produced may differ, as can the timings.
It can also stay around the house so feeding PRO PLAN LIVECLEAR should be included in your general allergen management routine.
