poor ratty, hope she feels better soon
i have been through this recently with my marmalade, he is now on cystaid daily as a precaution as he had 2 bad bouts one after the other. the vet also said to stop feeding him on dry food as he obviously wasnt getting enough moisture as he didnt drink much, since his diet has been changed and on the cystaid he has been fine
hopefully with ratty it is something as simple to treat
