Pregnant women can get toxoplasmosis from cleaning litter, which can affect the baby but does not harm the mother. The only thing that would concern me with an immune compromised individual is the possibility of Cat Scratch Fever. ANyone can get this infection caused by cat scratches, and it is easily treated with antibiotics, but I would be concerned with an immune compromised individual, simply because a normally innocous infection can become life threatening when the immune system does not work properly.

We have five cats. I took care of all the litterbox duties during David's treatment. We kept the rowdier cat away from David because he is always playing too rough and scratching David. Since he was told that he should not even use a razor (with the exception of an electric razor) during his treatment, it seemed prudent to avoid being scratched by one of our 'children' as well.

OTOH, our one cat who has been declawed was David's constant companion. We started calling her Nurse Betty (after the movie by the same name starring Renee Zellwegger). It has been 16 months and Nurse Betty still takes care of her 'patient'. If David says, "I'm sick" she comes running and starts head butting him and loving on him. The odd thing is that before he got sick, she was MY cat and would have NOTHING to do with him. Now she is more his cat than mine. She has a special kitty bed that is all hers, which sits near the foot of the bed. We call it the Nursing Station, because if David is in bed, Nurse Betty won't leave her nursing station except to use the litter box and eat...and she checks on her 'patient' exactly at 11pm, 7am and 3pm, any time he is in bed. Now that is a smart cat! LOL!
