Hi!
I did some research on rabbit insurance in the UK a while back, and could only find 3 companies that cover rabbits.
I went for Helpucover as it seemed to be the most comprehensive plan even though it was cheapest. I pay £10 a month per bunny, and I’ve claimed twice – once a £1500 bill and once a £100 one and they paid out with no fuss at all. I’ve been very impressed with them. There’s a £50 excess for each condition.
All the insurers seem to have restrictions around dental, as that’s a common problem.
I also fear in your case that stasis would count as a pre-existing condition. I recommend you give them a call though and see what your options are.
The other two that I found that do rabbit insurance are PetPlan and exotics direct, so perhaps it’s worth calling them all to ask what your options are.
I’m sorry that Theo keeps suffering GI stasis though! Can you identify any food triggers? Eg, did he get anything different over Christmas (Brussels sprouts? ?) that might have bothered him?
I fear that some bunnies are prone to stasis though. Sarahthegemini started a recent thread on it, as one of her bunnies has had stasis 3 times, at about the same age as Theo. She has cut a lot of veg out of their diet, so I recommend you read this thread for some possible ideas
