Solomon will get loose from the worming. That is normal and should pass in about 2 days. The blood does seem quite common bengals and you should mainly be concerned if it is all the time or a dark red in the poo meaning it came from higher up in the digestive system.
Try increasing Solomon's dry food intake Vs the wet food and see if his poop firms up - this worked within 2 days for my little guy and we have not looked back since. Just make sure any changes are gradual if he hasn't had the dry food before. Another thing we do if Chats has an upset belly is giving him plain cooked chicken for a few meals as this is easy to digest, like when we are sick and just want plain toast!
If you look under health care or nutrition there is much more info. You can also use the search engine for words like "bloody" "stools" etc etc.
Good luck!!
