“The key flooring to avoid for chronic cystitis is concrete as this pools the leaking urine which rots the skin of the feet. So she would be better on, deep litter, peat, saw shavings, straw indoors and grass or deeper sand (ie not sand covered concrete rock) outdoors in my opinion. The problem would be on deep litter indoors if she started to eat it, it could make things worse by causing impaction colic, or even poisoning if "treated" saw dust/shavings is mistakenly used. So observation is key and ad lib hay overnight to prevent this.”
