Thank you for your patience. There are a number of possible causes for Benjamin's soft stool, including anything from a sudden change in diet, to an infectious issue, intestinal worms or even an internal organ issue. First and foremost, you really need to ensure that Benjamin is completely up to date with his worming treatments. If you haven't done this for a while, be sure to get him treated with a reliable all wormer like Drontal or Milbemax.
If this diarrhea has continued and hasn't improved within the last 3 days, I do definitely think it would be worth getting a fecal sample off to your Vet. Here he or she can send this away for full analysis including a culture and fecal float to help rule out infectious causes such as salmonella, campylobacter, giardia, coccidia and intestinal worms.
For now you are best feeding Benjamin something really bland. Cooked, boneless, skinless chicken breast and cooked white rice is ideal for this type of situation and you can start that from the morning. If the diarrhea is the same consistency this morning as it was on day one, I would recommend getting a fresh stool sample along to your Vet tomorrow if they are open and if you can. Do your best to get a fresh sample in to an icecream container or something similar and take this into your Vet if there hasn't been much improvement.
Please also make sure that Benjamin is drinking plenty of water. All of this diarrhea could quickly make him dehydrated if he doesn't drink sufficient water. If he isn't keen on drinking, you could even try a chicken broth. To make this, just boil up some fresh chicken, scoop off the solids once cooked, and feed him the luke warm soup that remains.
