My cat has inflamed gums/running from food bowl

I wonder if anyone can offer some advice on my cat's mouth issues.

I noticed 2 weeks ago that out little boy Murphy started running away from his food bowl (and I mean bolting!).  He's always had a healthy appetite to we made an appointment for the vet straight away.  The vet thought it could be stomatitis after checking his teeth and gums.  He was given a steroid shot and an anti-inflammatory shot and we were told to bring him back in a couple of days.  Murphy's eating habits were back to normal by that evening.  

We went back on the Monday to the vets and the inflammation was still present.  To cut a long story short, and after 5 visits, he was brought in to test for FelV, FIV and Colitis.  He was an unneutered stray whom we adopted from a local shelter (now neutered).  

The vet gave him another weeks worth of shots (which wore off yesterday) and now we're back to him not eating as of last night.  I have been able to give him cat food with sauce and he's been licking the sauce.  Murphy's test results aren't due back until this coming week but I'll call the vet tomorrow and get him another appointment.

His symptoms are as follows:-

Bad breath.

Inflamed gums.

Very very strong smelling urine.

Scared of food bowl.

His coat (once glossy) is now dry and he has dandruff.

Third eye visible.

Depression and is much more "attached"

Sleeps alot indoors (he is an outdoor/indoor cat and spends alot of time outdoors).

What do these symptoms point towards.  I'm driving myself mad.

Thanks so much for any help.

Honestly, those symptoms you lists don't sound like FeLv or FIV, or certainly not Colitis!  If you had mentioned diarrhea amongst the symptoms, then I would re-think my comment.  But, really, it could mostly stem from his mouth issues.  Of course, I am not a Vet, and it's impossible to diagnose via the internet, even if I were.

I know it's difficult, but try not to start thinking "the worst" and do a lot of digging into what it MIGHT be, and since you've already had the tests run, try to wait for the results.  Then you'll know what you're dealing with (or at least know what it isn't(

What does he normally eat?  Is it wet food?  If not, can you tempt him with something nice and soft that doesn't require a lot of chewing?  And if he already eats wet food, maybe you could add some water to it to make it even more mushy, or even put it in a blender so there are no chunks of anything for him to have to chew?  He really needs to get in some nutrition.  Can he drink water okay?  If so, at least that means the action of licking isn't too painful, which means he should be able to lick a soupy food
