For a 9-year-old spayed female cat, which action is not recommended for a client concerned about toxoplasmosis during their pregnancy?

In the context of managing concerns about toxoplasmosis during pregnancy, recommending euthanasia of the cat if the titer for Toxoplasma gondii is positive is not advisable. A positive titer indicates that the cat has been exposed to the parasite, but it does not automatically mean that the cat poses an immediate or substantial risk of transmission. Many cats, especially those that are indoor and are spayed, have a low risk of shedding the parasite, particularly if they are not actively infected.

In contrast, encouraging regular veterinary check-ups is important for the health and well-being of both the cat and the owner, as it helps manage any potential health issues early on. Submitting a serum sample for Toxoplasma gondii titer can provide valuable information regarding the cat's exposure and risk level for the owner, enabling informed decisions about managing the situation. Advising the client to avoid direct contact with the cat may be a precautionary measure, particularly during handling of cat litter, to reduce any potential exposure to the parasite in feces.

Therefore, the action of recommending euthanasia fails to consider alternatives that can effectively reduce risk while also maintaining the human-animal bond, making it an inappropriate recommendation.
