firistly i dont belive cats, or any animal, to be "spitefull" i bleive its a human emotion that we place on our animals to feel better when we dont understand why there doing somehting or our own training methods have failed.
cats urinate for a number of reasons, STRESS being a big one and considering you call her a nasty cat it sounds like shes a very insecure kitty who needs alot of one on one and personal reassurance.
cats do NOT like change, they dont like change in routein they dont like new people, new places, new situatons, heck even a change in average temperature in a room can send a cat into a hormonal breakdown...
cats also urinate to mark their teritory, yes even females...insecure cats mark more frequntly, its comforting for them to be surrounded by their own scent, shes also claiming his main place (the bed) as hers, this is my person kind of behaviour.
she does need to see a vet to rule out UTI's but if this has been going on for a long time id put money that this is a behavioural problem from a very insecure cat.
the best ways to help with that kind of issue are products like feliway (comfort zone), and lots of one on one time.
the new kitten probably just agrivated the situation too.
some cats are also one cat kitties...its just the way it is sometimes, other times cats are terribly picky about other cats and who they like and dont like...
given that it sounds like the older cat is already very insecure, brnging a kitten in would just tripple the stress in her life and make her a very flustered, upset and "angry" kitty.
is mean kitty declawed?
and what kind of food is he feeding?
and is she spayed?
personally i would rehome the kitten, a kitten has a MUCH better chance of finding a home than an older cat with "issues" so i do give your frined a huge round of aplause and a thank you for choosing to rehome the kitten and keep the problem child...honestly this cat would probbaly end up being bounced around back and forth to shelters and probably wouldnt find a long term home given her current issues...offering her up for adiption would probably in the long run be a death sentence...people simply dont want animals with issues...even you said youd personally give away the mean cat...
its not her fault, a combination of genetics, and early socilization make all the difference, kittens should idelaly stay with momma untill 10-12 weeks of age because of these issues.
so offering a friendly kitten to a good home would get the best results.
now in terms of suggestions for your frined reguarding the older cat.
step 1: vet check, rule out health issues, litterbox problems are very frequently the result of other underling health issues. and its always better to be safe than sorry.
step 2: assuming health issues are ruled out...id suggest the plug in pet difusers, feliway is the cat one, its not cheap but ive found them to be a great help in high stress situations, they are pheremone based.
wash the comforter and her normal pee spots in natures miracle just for cats or other enzamatic cleaner, i usually throw it into the bleach cup for those with the feature, but if not i toss about a cup full in at the softener stage.
give her her own blanket on the bed, dont move it, and only wash it if she pees on it...if you ever have to go anywehre with her take the blanket with you.
lots of playtime...he needs to spend some serious 1 on 1 time with her, playing, snuggling ect...
good luck to him, its tough. cats are such tempermental animals that what they love one day could change the next...
but it sounds like shes in the right hands.
