Always cleaning my lop eared rabbit

Hi can anyone help? 3 year old rabbit constantly having to be washed due to loose poo sticking. Fed on excel and hay and mixed vegetables. Taken to vet poo sample sent no parasites, bio lapis given no real help from vet. Help please Justine

I think lots of people on here find Excel has given their bunnies soft stools.

Increased hay and less pellets and veggies might help.

I had the same problem when I fed one of my buns on Excel. I switched over to Supreme Science Selective pellets and this sorted out the problem straight away. Although I now feed my buns a mixture of Science Selective and Allen & Page Natural Rabbit pellets as Allen & Page are much cheaper than SS and also a bit higher in fibre.
This combination seems to work really well for both of mine, although they prefer the taste of the SS, they would have to like the most expensive one best wouldn't they!

Thank you i will give that a go
