Save Walter: Emergency Surgery Needed

We have had a hell of a year. A move because of a divorce, my fathers late stage cancer diagnosis. With help from a professional an emtional support animal was gotten. Then today happened. I was leaving for work and I did not know walter was by my car and i ran him over. He is at the emergency vet and needs surgery. But at this point our financial situation is maxed out. Please please helps us save our sweet walter. Hes just a baby and i cannot put him down. It would devastate us all
