Poor kitty! In a 13 year old cat, I strongly suspect that she has a medical problem causing these issues. Some common possible causes would include hyperthyroidism, diabetes, and chronic kidney disease. I would recommend taking her to the vet for an exam as soon as you are able to - he/she can do blood work and a urinalysis to help diagnose the problem and get her started on appropriate medication to treat it.

I know this can be very frustrating. If this is a new issue I would recommend taking Oreo to the vet to make sure she is healthy. Older female cats can get arthritis, kidney disease, urinary tract infections and even hyperthyroid issues that will cause abnormal urination. I would start off with blood work and a urine sample. IF all of Oreo's test come back normal I would recommend trying to increase the number of litter boxes in the house. Also try to identify anything that can changes or caused stress in the house. Feliway is a cat pheromone that can help decrease stress. You can plug them into your outlets and it is also available in sprays. I hope that helps

There is probably something medically wrong with her, it could be bladder inflammation, kidney failure or hyperthyroidism among other things, I would recommend taking Sadie to the vet and have a urine analysis done, this may give you an answer.

Thank you for using Petco Pet Education Center, formerly Petcoach! Inappropriate urination can be caused by bladder stones or crystals as well as behavioral issues. Other diseases such as diabetes and kidney disease can cause this symptom as well. I recommend having your cat seen by a vet to rule out these conditions. It may also help to provide an additional litter box (I typically recommend 1 litter box per cat and 1 additional litter box). I do recommend having your cat spayed to prevent certain cancers and uterine infections, but it may not help with this issue if caused by any of the causes above. I hope this helps and am happy to answer any other questions you may have!

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Poor Martha! I am not sure if you are referring to trouble urinating or defecating. If she is squatting to poop and nothing is coming out then she is likely constipated. Constipation in cats is not a primary condition but a symptom of something else (intestinal disease, kidney disease, etc). She should go to the Vet for an exam, a belly X-ray and have her anal glands checked. If she is severely constipated an enema may be needed. Also at age 9, I recommend blood work be done to check her thyroid and kidney values. Constipation in cats can be managed with diet and stool softeners. If she is straining to urinate then she could have a UTI, crystals in her urine or bladder stones. This also requires a vet exam. Try to prevent her from using the litter box for several hours before her appointment so the Vet can collect urine to test. Crystals and a UTI are diagnosed from a urine sample and bladder stones are diagnosed from an X-ray. Crystals are treated with diet and a UTI with antibiotics. Bladder stones are usually surgically removed but sometimes can be dissolved with diet. I recommend that Martha be seen today. I hope this helps and I wish Martha the very best!
