Table 3.

Cat counts and neutering percentage estimated using friendly vocalization without or in combination with food delivery. Data were collected by two observers during 2012 and 2014 over an overall length of 46.79 km and 54.08 km transect length, respectively, in the city of Rishon LeZion, Israel

Variable	Approach for observation	Cat observations (Observer 1)	Cat observations (Observer 2)
FRC counts [cats/km]	Friendly calling (mean ± sd)	16.1 ± 10.1	18.4 ± 9
	Friendly calling and food delivery (mean ± sd)	20.6 ± 10.8	22.7 ± 11.9
	Mean ratio between approaches (CI95%) p‐value	1.301 (1.212–1.396) <0.001*	1.219 (1.149–1.294) <0.001*
Neutering percentage [%]	Friendly calling (neutered/total cats)	721/1289 (55.9%) 967/1828 (52.9%)	892/1801 (49.5%) 1084/2235 (48.5%)
	Friendly calling and food delivery (neutered/total cats)
	Mean ratio between approaches (CI95%) p‐value	0.947 (0.859–1.043) 0.270*	0.991 (0.907–1.083) 0.839*
