Thanks for all your replies. The Panacur has arrived for both my rabbits and I will do my best to get that into them! (Wish me luck lol!)
I've been looking on the net about pinworms and it seems they are quite common in rabbits, but people just don't know it. They can cause all sorts of problems if left untreated long-term, but when bun passes away a post-mortem isn't done so they aren't discovered as the initial culprit
I've realised where they came from, I had been putting a swede out for them to munch on in the garden and often giving them a 'picnic' outside (God knows why I was doing that as there is plenty of grass lol!)....and I'd started to see slugs and snails appearing (where pinworm can be picked up from). I saw a large slug on their swede the other day and nearly had a fit and threw it straight in the bin. I'm sure this is where the problem has come from, so NO MORE PICNICS for them!
Thanks again,
Jo
