Why is my cat grumbling, straining, and has dark brown urine?

Pet's info: Cat | Domestic Shorthair | Male | 5 years and 8 months old | 13 lbs

My 6 year old tabby is grumbling when he bends. He's been to the box so many times today, but it seems he is constipated. His urine is dark brown. I can clearly see he's feeling a lot of discomfort. What can I do?

With his urine being dark brown I would be concerned about a possible urinate tract infection or even a partial urinary blockage. Make cats commonly develop sediment and/or stones in their bladder that can cause a lot of discomfort and even can block their urethra and prevent them from urinating. He could also be constipated and he may need an enema to help relieve him. I would take him to your vet to ensure his bladder isn't blocked or partially blocked because if this is left untreated it can cause issues with his kidneys from urine backing up or bacteria getting into his kidneys. Your vet will be able to palpate his bladder, run a urinalysis, palpate his colon to make sure he isn't constipated and even take X-rays if needed. Your vet will be able to come up with the appropriate plan of treatment to help him feel better. I hope this helps!
