I agree, it does sounds like a URI. There seems to be a lot of it going around at the moment....well there is in my house anyway!

Firstly my youngest cat Tigger came down with it, then my husband came down with a flu, then our eldest cat Louie came down with the URI, then our hamster had it and now after running around looking after all that lot i've now got it....I think my house needs fumegating!

Hope Ollie gets on at the vets ok...keep us updated.
