While Mom lived here, we had a felv scare. Salsa, our household pet show cat, escaped outdoors and engaged in a fight with a feral. Unfortunately, my mother did not tell me this had happened - she just let him back into the house. Later, when he seemed not quite himself, the story came out. He was tested for felv and found positive. This launched our cattery into a temporarily closed status, with strict quarantine and testing that took over six months to complete. At our six month recheck, we passed with flying colors - all our cats were negative for the fourth time. Losing Salsa was a hard loss. He was full of life and full of himself, and is sadly missed. We are now three years past this event, with no further problems.
