Scubadude, your cat had a urinary obstruction. Male cats (especially neutered males) are somewhat prone to this condition. Essentially a small plug of crystalline material will obstruct the urethra making it impossible for the cat to urinate.
They will go into the litter box and try and try to go, but they can't. The bladder fills up and becomes painful, so they howl. (Think 10 hour road trip with no rest stops).
Usually a little sedative, a urinary catheter, and some IV fluids will fix the problem. And a diet change will keep it from happening again.
I had a cat recently go through the same thing, but he didn't start doing the howl until it was too late to save him. We took him to the vet, and she said that if we had noticed within the first 24-48 hours it would have been simple to save him, but from his symptoms she said he had probably not used the bathroom in a week, but he never gave us any signs. He was a tough kitty, and yes, cats hide their illnesses
very well. We thought it was simple constipation, so we waited an extra day to take him in. His litterbox was in a secluded place so we didn't notice that he hadn't been using the bathroom, also we have another cat so the litterbox WAS being used.
I don't quite agree with what you said about it being a simple thing to fix. The vet showed us that the bill for the treatment would be over $700 and he had a very small chance of living a normal life after that. My mother's friend's cat underwent the treatment, and every year since she's been spending thousands of dollars keeping the cat alive; EXTREMELY expensive foods, and once or twice a year he would have to have the procedure done again.
The problem is, after they've had the procedure done they have permanent damage inside their kidneys.
In my opinion, if that is what is going to happen, it's not fair to the cat to live such an unnatural and painful life. I agree with you for putting your cat down, but personally I would have done a lethal injection, it's a much more peaceful way to die.
I'm very sorry for your loss, I'm still grieving over my poor lost Frodo. In the future, I will always take my cats to the vet at ANY sign of odd behaviour. I think you should keep that in mind for yourself as well.
Again, very sorry for you, it's always hard to lose a loved pet
