You should be fine, you are probably ommune already. If you.want to.know for sure ask your doctor.for.a.blood test. Not.all cats carry toxoplasmosis as well.
you must use rubber gloves if u are handling the wastes & wash ur hands properly before touching or eating food stuff that too must not come in contact with the cat
