One of my cats, Jesse has feline dementia. She is quite old, we're not exactly sure as she adopted us, but the vet estimates 13-15 yrs. Her kidneys are not great, but he says they are still functioning, but the dementia is really worrying me.
She has most of the symptoms, the worst being the howling at night. She sits in the kitchen howling in the most awful manner. It doesn't last long, but if you look at her eyes, you can see she is not "there". Once you pet or pick her up the howling stops and she goes back to normal. She also forgets that she has eaten and asks for food constantly, then looks at it and walks away. She does eat at her mealtimes though.
She also forgets to come to bed at night, she sleeps with us and the yorkies, and she will howl in the TV room as if she is lost

until I fetch her.
She has lost a lot of weight and is a shadow of her former self. She gets a vitamin shot every few weeks to perk her up and help with the dementia, but
I don't think this is helping anymore.
She very seldom leaves my side and is very needy. Do any of you have any suggestions on what I can do to help her, should I PHTS

The thought of that kills me, but if it is best for her?
