Why are my cat's testicles yellow and dirty? Should I be concerned?

Thank you for reaching out about Hamlet. His feces look very normal in consistency. The color change can be due to his diet or how he is digesting his food. I would not be overly concerned at this time. I wouldn't continue to monitor him. You can also have his feces tested to ensure he does not have any parasites.

Yes, I agree that the scrotum appears to be red/irritated. I would not be overly worried at this stage. I don't think it is anything serious but he definitely needs to be seen by your vet. It looks like it may be a superficial skin infection.

As long as it is the fur that is turning yellow and not the skin / gums / conjunctiva / nail beds, it isn't very concerning. It actually looks like it was caused by something environmental, or, Domino had something in his mouth that was yellow and cleaned the same area repeatedly causing this result. I have also seen this discoloration occur in animals that are stained with urine, though this would be a very unusual location for that to occur. If he is acting completely normal, I wouldn't lose any sleep over this. Hope this makes sense!

It could just be scar tissue but I would strongly recommend to have your vet just take a peak at them . Your vet will be able to palpate them to ensure there isn't any infection in that area and ensure he doesn't need any antibiotics. I cannot say for sure if they are okay with just a picture. I hope this helps!

If it is not dirt and will wash off, then he needs to see the veterinarian today. Black discolored tissue often indicate significant injury and even tissue death. This requires treatment quickly. Best of luck and please feel free to post any additional questions.

Thanks for using Petco Pet Education Center, formerly Petcoach! Yellow/beige could be diarrhea, but it also could be pus. Either way, it is not normal. I recommend taking Chip to the vet to look for an abscess. This needs to be treated with antibiotics and pain medications. Good luck and kisses to Chip!

Hi and thanks for using Petco Pet Education Center, formerly Petcoach! The strong ammonia smell is likely due to the urine being concentrated (not diluted by water intake). Male cat urine also has a special "scent" for marking. Neutering will help with this. The yellow stool will require a fecal from your veterinarian to check for parasites. Hope this helps!
