Thank you Rosella and Andrew
Archie has been tearing round this evening and it is a long long time since he last did that
I am beginning to think he may have had this parasite for a few years now
He used his litter tray this evening and I cannot remember the last time there was no whiff like now.
It just makes me think how many time are our cats being diagnosed with colitis without testing them thoroughly.
Archie may well have colitis but this in my mind has been troubling him for an age.
Would not want anyone else to go through this
