We all knew this day would come. Those kittens are better off. Tammy being unable to care for them is proof she hasn't lost an ounce despite claims otherwise. She will be bedbound before long at this rate.
Once the kittens got bigger she likely lost interest anyway. The way she went on about wanting a puppy or kitten because she was lonely might have been true. But reality is harder to deal with. At the doublewide she was not responsible for the family pets. There was a video where she was yelling at Dustin to feed the cats. Losing Dustin must have been hard on Maw & Paw. Back to the reachin' stick.
Hope the kittens find a nice home.
