Hi thanks everyone, just got home from a meeting, Cleo is totally back to normal, running round like a mad woman. Ralphie is also much better but not as alert or lively as normal!!!
I hope it was just a bug, i've been trying to work out if it could be something they ate but i don't know. Ralph is still house bound at the mo so only eats his dry biscuits, Cleo is out in the garden most of the time and they don't mix as they don't like each other.
Fingers crossed that's it now, i'm just hoping Jet doesn't catch whatever they had, i'm fed up of cleaning carpets!!!
