* Biting and fighting activities. Infection by this route has not been able to be demonstrated experimentally.

*[[Fleas|Fleas]]. The fact that Mhf infection can be prevalent in areas where fleas are uncommon makes this less likely<ref name="Jensen"> Jensen WA, Lappin MR, Kamkar S et al (2001) Use of a polymerase chain reaction assay to detect and differentiate two strains of ''Haemobartonella felis'' in naturally infected cats.
