San Antonio animal welfare staff members say a 26-pound tomcat faces a long road to recovery after his rescue from a neglectful home.
City Animal Control Services is offering Melvin for adoption, along with 20-pound Marvin, who also was rescued from the home.
Dr. Marilyn Gotbeter, the agency's chief veterinarian, said the cats "were cruelly confined, didn't have enough room to roam around and had no form of exercise or activity."
She said the animals gained weight from lack of exercise until becoming too fat to exercise. Melvin and Marvin worked out with doctors but quickly grew exhausted despite barely moving. In Gotbeter's words, "They basically pass out."
The vet said the cats are shy but sweet, and recovery is possible with a caring owner.
