very naughty maine coon

Question
Norman,  i have a female Maine coon called freeya who is 5 years old. When i first got her, she was a playful kitten and had a reasonable temper for her age, but she had a litter of kittens at 2 1/2 yrs and since she has been neutered she has been awful.  she wee's everywhere from kitchen surfaces to shoe box's, she scratched a leather suite and our livingroom wallpaper so badly they had to be replaced.  She has scratched door facings and skirting boards all through the house and she bites and scratches all the time as well as the usual hissing and growling. she is fine with me as im her "mum" but she has a big problem with everyone else at home.  Im unable to groom anywhere apart from her head and shoulders as soon as i get past there,  she bites and runs off.  I have resorted to getting a small garden shed for her to stay in all night as she would keep the entire house up all night with her scratching doors and jumping around. I really don't want to give her away as she is my pet and i love her to pieces, but I'm at my wits end! please please help!
kind regards
Laura

Answer
Laura,

Let me understand this better.  She began this behavior after she was spayed?  How long ago was that?

For some of the behaviors, like the scratching, does she have a normal cat exercise post?  These should be sturdy and tall enough for the cat to stand on its hind tippy toes and extend its front legs up over its head to scratch.  By sturdy, it should not tip or move.  Usually a wide base or a base with a cubby hole and a 4 X 4 wrapped in closed loop carpet or sisal or both is a good choice.  If there are shelves to perch on. so much the better.  Sometimes if the cat does not take to the exercise post right away, we spray it with catnip spray or honeysuckle spray.

I have also seen cats react to the anaesthetic and become almost intractable whereas they used to be sweet.  They often grow out of this (usually after a few months to a year).  There are some medications that might work to mellow the cat, but you will have to consult your vet.

Other than that I have nothing else to suggest.

Best regards... Norm.
