My eyes swell up and itch like mad if I touch them after stroking any animal, be it dog, cat or rat. I have to be very careful. The chemist gave me phenergan tablets, which are antihistamine, and some drops, could have been the same - phenergan! Anyway, that sorts it. Talking about things we can catch from our pets - when we lived in South Africa and when I used to deworm our pets, I dewormed all of us too at the same time - it was common practice. I don't see the same here in Britain though. You would be surprised as to how many of us have worms that we have inadvertantly picked up from our pets, or from other sources and with Britain being a country of animal lovers, I am surprised that deworming of people, especially children is not more widely advocated.
