Relationship of FeLV disease classification to sex^a

Group classification	No. of cats
	Female	Male
Progressive	18	13
Latent	2	0
Regressive	3	5
Regressive/abortive/uninfected	6	15

^aMales had proportionately more regressive/abortive/uninfected infections than females (χ² = 6.93; P = 0.045), and females had proportionately more progressive infections than males. Three cats did not have gender recorded at the time of sample collection and were excluded from this analysis. Chi-square P value was simulated using Monte Carlo simulations, owing to expected values of <5 in latent and regressive disease classifications.
