For ages Mouse has done plentiful poo but its too small. She eats a little hay, unlimited fresh forage (lots) including grass, some dried forage & SS nuggets. Her vet wants her on more nuggets but she isn't that keen. I was wondering about giving her Protexin Pro Fibre daily. But I don't really like the ingredients

Wheat feed, Alfalfa meal, Sugar beet, Psyllium husk, Wheat bran, Lignocellulose, Linseed, Preplex prebiotic (Fructo-oligosaccharide)

She has a delicate stomach now she is old & frail

She also doesn't drink. She wee's fine & it looks healthy for rabbit wee so assume the forage is providing some hydration

Any ideas on how to get more fibre in to her & any views on protexin?
