Hi there. I'm sorry to hear that Tofu is not feeling well. At his age I would be worried about a virus, parasites or an intestinal obstruction. Those are going to be the most common things. Other possibility is that he was born with a problem with his kidneys or liver. My best recommendation is to take him to the vet for an exam and some bloodwork. That can rule in/out many of the things I mentioned above. Of course more testing may be needed like a fecal test or x-rays. It will depend on what the vet finds on the exam. Unfortunately his symptoms are very vague and could be a sign of any of those diseases (and more). They are not specific signs for any one disease process so I cannot pinpoint exactly what is happening just based on your description. If he is sick, you need to get him to a vet as soon as you can. I hope this helps. Best wishes to you and Tofu. I hope he is back to feeling better soon!

    Sorry to hear about B. Based off of what you're describing it sounds like she is pretty sick and one thing I would be worried about is diabetes. I would also be concerned with her having kidney disease, pancreatitis, or some form of cancer. My best recommendation would be to take her to her veterinarian for an exam and blood work at the very least. I hope she gets better soon!
