My 14 yr old cat has been eating more, drinking noticeably more water and appears to be losing weight. He's both an inside and outside cat and does occasionally catch and eat baby rabbits and chipmunks. He also seems a little more lethargic. Thanks.I live in a normal one person household with my year old neutered male cat …
I live in a normal one person household with my year old neutered male cat in the high desert of Nevada. I only feed my cat Purina ONE and give him a can of tuna as a treat on Sundays. He comes and goes as he pleases through a cat door and I do not need a litter box. Every single day of his life he brings home live prey and slaughters it in the master bath tub after he gets bored playing with it. His prey consists of birds, lizards, chipmunks, field mice and snakes. Last week he brought home a live baby sidewinder. Am I doing something wrong or is my pet a natural born killer? I would like this behavior to stop but I still want him to be a cat. Help.My cat is 19 years old. He has slowed down considerably, as can be expected…
My cat is 19 years old. He has slowed down considerably, as can be expected, but just in the past week or so he has cut back his eating to almost nothing and has lost weight. Is this a sign his time is up or an actual problem?My cat is 21 weeks old and has been breathing heavily after playing and som…
My cat is 21 weeks old and has been breathing heavily after playing and sometimes she breathes hard for no reason at all. What do you think is wrong with her?What is the best Purina cat food to promote healthy elimination? My cat’s …
What is the best Purina cat food to promote healthy elimination? My cat's feces are dry, she's 10 years old. Also, her sister has stopped grooming I suspect because of a hairball that she's having trouble with. The vet prescribed cat lax twice a day for two weeks & I'm finding this impossible to give to her because she squirms & cries each time we try to give it to her.Squamous Cell Carcinomas in Cats

Bexfield, N. H., A. J. Stell, et al. (2008). "Photodynamic Therapy of Superficial Nasal Planum Squamous Cell Carcinomas in Cats: 55 Cases." Journal of Veterinary Internal Medicine 22(6): 1385-1389.Squamous cell carcinoma (SCC) is a common skin tumour found in cats. It often affects areas that are non-pigmented and with little hair, such as the nose, eyelids, and ears. Conventional therapies for SCC include surgery and radiation. Photodynamic therapy (PDT) is a cancer therapy that uses visible light to activate photosensitizer agents that localize in the target tissue. The photosensitizing agent 5-ALA can be administered topically, and has previously been evaluated for feline cancer therapy in a small study. Fifty-five cats with SCC of the nose referred to the Queen's Veterinary School Hospital (University of Cambridge, UK) were enrolled in the prospective study. The 5-ALA cream was applied topically every 30 minutes for a period of 6-8 hours. The cats were lightly sedated and medicated for pain, and all wore an Elizabethan collar. Illumination of the lesions was performed with light emitting diodes while the patients were under general anesthesia. Cats were reassessed one month after PDT. Outcomes were defined as complete response, partial response, or no response. Ninety-six percent of the cats responded to therapy, with 85% having a complete response. However, there was a recurrence rate of 51% at a median interval of 157 days. Although PDT does not lead to a complete remission in all SCC cases, it has the benefit of being safe, well tolerated, and cosmetically acceptable.
