Note: Odds ratio (OR), 95% confidence interval (CI), and P value for significant association with positive results of PCR testing for T. foetus are shown for each variable. Breeds represented by fewer than 10 cats (number of cats): Norwegian Forest cat (8), Balinese (7), Exotic shorthair (7), Tonkinese (7), Birman (6), Egyptian Mau (6), Russian Blue (6), Scottish Fold (6), Ocicat (5), Oriental shorthair (5), Manx (4), Somali (4), Japanese Bobtail (3), Pixie‐bob (3), Bombay (2), Cheetoh (2), Havanese (2), Singapura (2), Australian Mist cat (1), Chartreux (1), Ragamuffin (1), Serval (1), Snowshoe (1), Thai (1), Turkish Angora (1).
Breeds represented by fewer than 30 cats were combined and used as the baseline category for the logistic regression model.
