There are some groups that can help pay for the surgery if you need assistance.
Check out these links and see if they can help. I recommend contacting uan first. They have a great staff and people respond quickly. Here are some organizations that help individuals as well. Help-A-Pet http://www.help-a-pet.org Focuses on helping low income individuals with all kinds of vet work, including preventative care and non-emergency treatments. They work with all kinds of animals. IMOM http://www.imom.org Focuses on emergency medical care for dogs and cats that require expensive treatment to live. United Animal Nations http://www.uan.org/ Focuses on disasters and helping low income individuals or rescuers. They work with all kinds of animals.
