This makes me suspicious that one of the cats may have diabetes. If any of the cats are drinking more water or urinating more frequently then that would increase my concerns of diabetes. Also, are any of the cats losing weight? I would encourage you to consider having your cats evaluated by your veterinarian soon. Best of luck and thank you for using Pet Coach.

    Possible and common differentials for this presentation are diabetes mellitus, renal failure (eventually with urinary tract infection associated) , hyperthyroidism, liver problems. A check up urine analysis and a blood test would be the first steps to start investigating the problem and reach a diagnosis.

    Please do not hesitate to contact us again on the forum or by requesting a consultation (where you can post pictures ) if you have any more questions or to discuss it any further.
