Over protective kitty??

when my cat died 8 hours after giving birth. her babies needed to be taken care of and after three days of hand feeding them i found a foster mother that had a inbred child that was two weeks older then my babies. we named the foster kitty Pudgee. she tradgically died a few months ago when she was got caught under my bed...it crushed her. ever since then my male cat Norm (that came from the mother that died) has been peeing on the floor next to my bed and also in all the rugs in the house and has been more affectionate with me. is this in reaction to her death or something else. he is not yet neutered for good reason....he will be but not before we keep the blood line of precious, the mother that died. we will keep one kitten and the others are already spoken for even though they arent yet born. what can i do? is he stressin or is this normal? could he just be spraying? my roommates female is not yet spayed...has a appointment...she is 7 months and he is 5 months. what do you all think
