    Do not allow your cat outdoors or you may lose her for good. Animals that don't feel well will often hide hoping to get rest and feel better when in reality she may not be strong enough to make it back home. A 10 pound weight loss is a huge amount of weight for a cat and signifies something serious is happening internally. Worms in an adult cat that is healthy and immunocompetent (meaning her immune system is working properly) rarely cause any symptoms. She needs an examination and diagnostic tests including a complete blood count, tests for Feline Leukemia and Feline Immunodeficiency Viruses as well as a complete biochemistry profile and possibly some radiographs. Metabolic diseases that can lead to her symptoms include kidney or liver disease, diabetes and hyperthyroidism which if left uncontrolled can lead to heart disease and secondary organ failure. Please get your cat to her veterinarian as soon as possible.

    My kitten was dewormed about four or five days ago (for the first time), and probably had worms prior to deworming, and now I think he's constipated.

His belly is really swollen and I'm nervous that he's constipated. I'm also unsure as to whether I should allow him around my other cats if he had worms, or is that okay once he has been dewormed?
