Oh, that sweet little old lady

She doesn't have CHF, she is just getting older. But, as my vet says, old age is not a disease.
Love her, hug her, video her, kiss her. Whatever she likes to do, she gets to do.
I used to take this time and make it special; make warm oatmeal with Nutrical added; add some Green Mush (see Kim's Ark for more info). Yogies, ice cream, anything to keep the weight on. She will love the extra attention, and you will treasure giving it to her.
Weigh her more often to make sure she's not losing too much weight; it's hard to tell without weighing her. Make oatmeal, and add peanut butter..whatever will put weight on.
As far as what to clean her with, I used to use Johnson's baby shampoo. It makes them smell so nice, and is very gentle.
She is so very sweet; what a special video. Please give her a special kiss on that little head, from me

Oh, you might want to block off the second level, so she doesn't make a mistake and get hurt. Your attention will make losing the second level worth it.
