Quimby went to my vet yesterday for neutering. Only one of his testicules had dropped so she had to go looking for the other one. She also removed two lumps from him. One is a mass cell tumor. My sister talked to the people who had Quimby before. They had been taking him to Companion Pet Clinic. They had been told the lump was a cyst, and had taken him back twice to have it checked. Could a cyst turn into cancer? Could my vet be wrong? She detected a heart murmur when I brought him in for a check up, previously. They had never mentioned anything about his heart murmur. I was planning on only fostering Quimby until we could find him his new forever home. It looks like it was just meant to be. He came into our life's so we could take care of him. Hubby is starting to soften. My biggest concern now is the tumor.
