My Cat's Tongue Is Red And Swollen. He Licks His Lips And Smacks. He Is Also Starting To Smell Of Urine, But I Think It's Because He Cannot Clean Himself. What Could Be The Cause?

You really do need to get the kitty to the vet. If the tongue swells up too much, then he could literally suffocate to death. Hope this helps - good luck to you and the kitty.
