If you or your cat are very sensitive to odours, if you have more than two cats, senior cats or non-castrated males, your best option could very well be the “Odour-Lock™” formula (City or Extreme Classic).
Si les odeurs vous importunent particulièrement, si vous avez plusieurs chats, des chats âgés ou des mâles non-castrés, la formule Neutralise-Odeurs™ (City ou Extreme Classic) saura vous donner pleine satisfaction.
