I can help however could you please answer the following -
When was his last bowel movement?
Do you suspect what is causing the constipation - did he eat something unusual or get into anything he shouldn't have?
Is he eating and drinking?
Is he urinating normally?
I'm very concerned about the fact he cannot urinate. This is a sign of blockage (i.e. crystals) and if left untreated Kaiser's chances are not good - this is a serious problem. You have to take him to the vet so he can drain his bladder/remove the blockage and prescribe the necessary med's and diet.
If he also has gall stones, this is adding to the problem of compromising his health.
With Kaiser in this condition and in so much pain, you will have to find a way to get treatment. Ask your vet for a payment plan; call other vets if needed and ask if they will offer a payment plan; call your local humane society or animal rescue groups - many times they work with low cost clinics and can refer you to them. You shouldn't take too much time finding where to go and what to do - this is an emergency situation and needs to be taken care of ASAP!
I do not feel comfortable offering constipation remedy's at this time because of the fact of his overall health condition being so serious, I do not want to jeopardize his health even more.
Jamie, Kaiser needs you right now - more than ever. I'll be here if you need me but please consider what I have said okay? Let me know if you go to the vet; the outcome; and if there is anything else you need.
