Schematic plot of the cat facility floor plan. The cats were housed in the combined cat rooms 1 to 4 (total 37.2 m²; dark orange) within the inner barrier area. The cat rooms were connected by open windows. The cats came into the clinical examination and blood/sample collection room once a day, still within the inner barrier area. They had no access to any other rooms. Only the light orange area was disinfected daily with sodium bicarbonate and Incidin^TM Plus. ①: Outer barrier. ②: Inner barrier. Not drawn to scale.
