Save my daughters best friend

I've wanted to be a father and husband forever   I'm very fortunate to have found not 1 but 2 loves of my life. From the first moment, I saw these 2 beautiful , girls I lost my heart, I just wanted to be able to take care of them and provide for them  I've been able to do just that, and have been absolutely honored to do so  with all my heart . My beautiful daughter, has been through an unimaginable heartache this past month, her biological father, was a good man and  father,but unfortunately couldn't Cope any more with life and decided to end it on April 11  yesterday her beloved  2 year old cat Oliver was rushed to the hospital with severe pain, we were told he has a urethral obstruction. As a man and father I'm heartbroken that I can't afford to pay all of this, we have paid our last $800 last night to temporarily unblock his obstruction but the doctor said it would only provide relief for 24 hours  and then he would need to go back for the surgery or we will have to put him down. Any little bit of money ,will help save my daughters best friend . Thank you
