Can i just ask where you got your peridale granules and RC intense hairball dry food?
Both from VetUK - I checked and they are the cheapest. Still annoying that something that probably cost pennies to make is £15 for 175g - some online places charge £20+ so vets much charge even more.
I like the fact that my vet wanted to start simple. Although I wasn't given any advice, I think the extra water is really important and probably AS important as the bulking. I didn't think Cistapride was available any more.
From my own experience having chronic IBS, the consultant told me that regular laxative use weaken the muscles so should be avoided if at all possible.
On a brighter note - His favourite place to eat is the window ledge. He is quite capable of jumping up there but waits for me to lift him up - even though I see him several times a day - it hit me tonight how much heavier he is in just 12 days - he is even getting a little paunch
Also a bitter-sweet thing - he started off very needy and trailed me around like a lost lamb. After he had eaten tonight, he went under the bed to have a wash rather than trot back to me. I know it is a good thing but at the same time, choked me a bit
