Are pregnant women with cats at risk of toxoplasmosis?

A long-standing belief suggests pregnant women should avoid cats due to toxoplasmosis, a parasitic infection that could harm unborn babies. This has unfortunately caused many cats to be given up when their owner becomes pregnant. But what does the latest evidence say? Can owning or interacting with cats during pregnancy truly increase risk, and how can this be managed safely? This article explores toxoplasmosis risks linked to cats and offers practical advice for responsible cat owners during pregnancy.

Understanding Toxoplasmosis and Its Impact

Toxoplasmosis is caused by the parasite Toxoplasma gondii. Many adults may carry this parasite without symptoms, or with only mild flu-like signs such as swollen lymph nodes. Those with compromised immune systems and pregnant women are at greater risk of complications.

Around a quarter of people in the UK may carry the parasite at some point, yet serious illness is rare. The main concern in pregnancy is the transmission of toxoplasmosis to the unborn baby, potentially causing congenital toxoplasmosis. This can result in premature birth, low birth weight, or long-term disabilities affecting vision and brain development.

Cats and Transmission of Toxoplasma gondii

Cats become infected mostly by eating infected prey or raw meat and then shed parasite eggs called oocysts in their faeces. However, only cats who hunt or eat raw meat typically carry and shed the parasite. Cats that remain strictly indoors and eat commercial cat food have a very low chance of carrying toxoplasmosis.

Importantly, cats only shed the parasite once or twice in their lifetime, for a brief period spanning one to three weeks. During this period, millions of oocysts may be released and remain infectious in the environment for months. Due to this limited window of infectivity, continuous risk from cats is low but specific hygiene is crucial to avoid exposure.

Practical Precautions for Pregnant Women with Cats

Pregnant women do not need to give up their cats but should follow these responsible precautions to minimise risk:

• Avoid cleaning the litter tray if possible. If you must, always wear disposable gloves and wash hands thoroughly afterwards.
• Change cat litter daily. The parasite becomes infectious only 1-5 days after being shed in faeces, so regular cleaning reduces exposure.
• Ensure cats are kept indoors or do not hunt. Indoor-only cats have a very low risk of toxoplasmosis.
• Do not feed cats raw or undercooked meat. This prevents them becoming infected.
• Maintain good hygiene when handling raw meat, washing fruits and vegetables, and washing hands regularly. Toxoplasmosis can also be contracted from contaminated food or soil.

Frequently Asked Question: Can you catch toxoplasmosis just by touching a cat?

Quick Answer: No, toxoplasmosis cannot be transmitted by simply petting or touching a cat.

The parasite is spread through infected cat faeces, not through saliva, fur, or casual contact. Petting your cat or being near them does not pose a meaningful risk. The main concern is handling litter trays where infectious faeces may be present.

Summary and Reassurance for Cat Owners

In summary, pregnant women with cats can continue to enjoy their pet safely by observing sensible precautions, especially around litter hygiene. The parasite responsible for toxoplasmosis is only shed briefly by cats, predominantly those that hunt. Indoor cats on commercial diets present minimal risk.

Maintaining good hygiene, avoiding contact with cat faeces, and practising food safety around raw meat and unwashed produce are key to protecting mother and baby. Pregnant women do not need to part ways with their feline friends but should take simple steps for peace of mind and health.
