Discussion Overview

The discussion centers on whether cats can become infected with bacteria or viruses from playing or hunting rats and mice. Participants explore various pathogens, including rabies and toxoplasmosis, and share personal anecdotes and theoretical insights related to this topic.

Discussion Character

  • Exploratory
  • Technical explanation
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • Some participants propose that cats can theoretically become infected with rabies if they encounter an infected mouse.
  • Others mention that not all exposures to pathogens will result in infection, citing a case where a girl contracted rabies from a cat, but the cat was not found to be infected.
  • Participants discuss toxoplasmosis, noting that it alters the behavior of rats and mice, making them easier prey for cats, and clarify that it is not a bacterium or virus but a single-celled organism.
  • One participant shares a personal experience with a cat that contracted salmonellosis, highlighting that food-borne illnesses can affect animals similarly to humans.
  • There is mention of various pathogens that can be transmitted from rodents to cats, emphasizing the commonality of parasitism in nature.

Areas of Agreement / Disagreement

Participants generally agree that cats can be exposed to pathogens from rodents, but there is no consensus on the likelihood of infection or the specific pathogens involved. Multiple competing views remain regarding the implications of these interactions.

Contextual Notes

Some claims rely on theoretical understanding and anecdotal evidence, and there are unresolved questions about the conditions under which infections may occur.

I once saw a cat in the streets playing with a living mouse. The mouse wasn't moving, but it was breathing. The cat moved it from paw to paw and then took it in its mouth and moved it to another place where it kept playing with it.

Can a cat become infected with bacteria or virus for playing/hunting rats/mouses?

Theoretically yes, my understanding is that any mammal can be infected with rabies, if the mouse is infected then the cat is exposed.

I see. Thanks for replying.

I was a little bit curious.
 
Yes - toxoplasmosis actually alters rat and mouse behavior such that the prey become easier for the cat to catch.

In North America ~23% of adults have been or are currently infected with toxoplasmosis.

And yes, there are both bacteria and virus diseases that are transmitted from small rodents to domestic cats. Toxoplasmosis is a single celled organism related to malaria. Not a bacterium or a virus.

Very informative. Thanks!

It calls my attention how toxoplasmosis alters the rat and mouse behavior. I find it interesting and curious for something to alter the host behavior in such a way that increases its chances of multiplying. Very interesting indeed.

The reason I used the words "theoretically yes" is because not all exposers will result in an infection. There was a case in California where a young girl contracted rabies from a cat that was around her school or neighborhood. The CDC confirmed that she had rabies. They said she was fully infected and was treated but she was expected to die but some how she recovered. All of the stray cats in the neighborhood were captured and none of them tested positive for rabies. It was postulated that the cat had either ran off and died, or that one of the captured cats had recently attacked a rabid animal and the scratch the girl received inoculated her with the virus.

Hmm. Humans get all manner of pathogens from what we eat - Listeria, Salmonella, tapeworms, pinworms - (like @lisab above) so it should come as no surprise that food-borne illness should be something that happens to many animals. Parasitism is exceedingly common in Nature, simply because it is such a great way for organisms to thrive.

PW Ewald provided a lot of primary research and helped to define the field of the Ecology and Evolutuion of parasitism. from 1987

I also think that rabies can affect cat too.
