Please help save our little Merlin's life.

Our cat Merlin (6, male) just a day ago was diagnosed with Feline Urethral Obstruction, which means there are objects in his urethral tract, causing him an extreme amount of discomfort/pain and making it impossible for him to urinate. We went to a vet clinic last night where they cleared the obstruction but did not keep him for observation and aftercare because we couldnt afford the bill for that much treatment. And he seemed fine up until very early this morning, and again is not able to use the bathroom and is in such bad pain he is hiding under our bed, which if you know cats, that's not a good sign.

You might not know us very well, or you might. But any help would mean do much to Trisha and I. Merlin means the absolute world to both of us but especially to my partner Trisha, and if anything ever happened to him she would be devestated. if we have to make a more difficult decision about how to proceed from here if unable to get the funds necessary to get him treated fully, that will be even harder for her to bare. Merlin is such a silly, warm and friendly cat and the most affectionate cat I've ever known. No cat could be as affectionate as he is and right now he needs your help.
