Is the prayer of one who discovers cat feces under his bed after praying valid?

Prayer on a bed is permissible and valid. The presence of cat urine under the bed does not affect the validity of the prayer. What is required is the purity of the worshipper's garment, what he carries, and what his limbs touch. The presence of impurity near him or under him does not cause harm if there is a barrier between him and it.
