Save Jonny

My cat Jonny needs emergency medical attention for a urinary blockage. He can't go to the bathroom and his bladder is the size of a tennis ball, he will die if we don't have an emergency medical procedure to unblock his urinary track. I'm asking for help because he is so important to my boyfriend and myself, he is the sweetest boy and a huge part of our lives, I can't bare to watch him die. He is so loving and full of energy and his baby sister would be crushed if he passed away, he is everything to her and I can't imagine what it would to do her. Anything helps and would be greatly appreciated
