Elmo and I need your help!

Everybody knows how important their pets are, well for me Elmo is my everything. Everyone who knows me will know about my own struggles with mental health, through all this Elmo has always been by my side to offer comfort. At times he has saved my life. He is the most loving and gentle cat. Elmo has had some health problems over the years which have resulted in multiple vet visits. He has a heart murmur which means the vet believes that this is the cause of his 'episodes' he has been having. During these episodes Elmo becomes floppy, sometimes lifeless, his breathing gets insanely fast and his heart beats so fast the vet can hardly hear it. Elmo's presentation is abnormal and he is of high risk of serious complications.To try get to the bottom of this problem and to give Elmo the best life he deserves- the next step is a holter monitor tracing his heart for 24hrs. Please help us, any small contribution is another step closer to getting Elmo the treatment he needs.
