It is my personal belief that for some people there is an irrational fear of zoonotic diseases affecting cats. Or there are people who have an anti-cat agenda because they are predators killing native species who prefer to exaggerate the dangers of the spread of these diseases from cat to human to ensure that they are confined to the home and to try and limit the cat’s popularity as a companion animal.
Personally, I don’t see the big problem. It is unfortunate that domestic cats carry these diseases particularly Toxoplasmosis but there it is. We should take sensible, proportionate precautions and not use the diseases to leverage a personal agenda.
