Cat with FLUTD?

I have an 8 year old neutered indoor male cat who last year was diagnosed with FLUTD. 

He was straining and peeing blood at the time.  he had surgery to remove stones (which were not in his bladder after they opened him up) and went through a variety of meds during recovery.  This change in his health coincided with me taking him off of the raw meat diet I had him on, but I only noticed that in retrospect.  It also happens that we had a baby that year which has come to be a huge part of the problem.   After his FLUTD symptoms got better, he began spraying in the house.  He had never done that before. 

Over the course of the past year, we have tried Feliway, giving him more attention, homeopathy, Bach Flower Essences, more litter boxes, etc.  His spraying has gotten worse and his attitude is very sad and reclusive.  It is clearly my son who upsets him and he won’t even accept love and affection from me anymore, because he associates me with my son.  We have tried to find him a new home but cannot find someone to take a cat like him.  We would like to try again to help him feel healthier.  I am going to return to the raw diet.  Do you have any other suggestions for him?  Also, we spoke with a few animal behaviorists who said nothing will likely work for him except putting him on Prozac.  I have never been much of a drug fan but our house is getting destroyed and no one else will take a cat that sprays, who is 8 years old. 

What else can we do and if we end up putting him on Prozac what can we do to support his health? 
THank you very much, Kim C.

Wow what a situation! I admire your tenacity and thank you!

I would get back on the diet you were on before. Cat Boxes all over the house may help, especially those places he has sprayed but the key is plenty. I would also suggest our Omega Coat Check oil at 1/4 teaspoon daily. anytime  I have nerves/brain etc involved it is important to get extra Good fatty acids. It is the best I have been able to come up with.

I would also consider our Aller check for pets to help boost the immune system. Our Human supplement called REDOXX may help detox as well as help mentally. (many humans report really feeding better and actually many getting off drugs etc. One was on anti-depressants for over 12 years).
