Help Save Mortimer’s Leg

Hi my name is Quinn Larkin, I am a student at Indiana University and this is my 3 month old cat Mortimer. I took him home from a local shelter around 3 weeks ago. My adoption was delayed because they found out he was limping a little bit. I was able to get him 2 days later as they informed me that his limp was a minor soft tissue issue that would go away within two weeks. Three weeks later and his limp was worse than ever. I took him to an animal hospital where they told me he would need to amputate the leg or get an Orthopedic Surgery that can cost thousands of dollars. I am asking for your help and support in order to make sure he can grow up healthy and mobile. Please if you could spare even one dollar, anything can help. Thank you so much.
