I am sorry your boy is not feeling well and you did not receive an answer last night.
Can I please have more information about your boy?
Is he able too urinate?
Has he been outdoors?
What and when did he eat last?
Does he have any other medical issues besides hyperthyroid?
After your reply please give me a few minutes to type detailed answer or if you prefer we can speak on the phone.
