Hi Arthur,
I am sorry haven't gotten the tag to your post earlier but I can see that others gave you great suggestions.
Boo has been home for a week and I am seeing little change.
Forgive me but one week after such serious procedure as etube fit is still early days.. My cat has her tube in for just over a month and her demeanor and behavior was very much like Boo's. She'll get back to norm once her appetite returns and her Bg numbers are in the good range. Hang in there - she went thru so much, just give her some time.
Ducia was taking anti nausea pills Cerenia - 1/4 20 mg pill every 24 hours and a dose of antibiotic for ten days and I think it helped a lot with improving her appy. We never used appy stimulant medication but I heard it works well with Cerenia.
If Boo were my cat here is what I would try to do: start feeding her via tube as you usually do but stop after a little bit and offer her - bring to her face - a bowl of her favorite food - I hope she has favorite low carbs canned food - and add some warm water to it.
You can sprinkle it with a little Parmesan Cheese (dried or grated) or put some FortiFlora probiotic powder on top of it, and see if she'll show any interest. Even a little licking is a progress at the beginning. If she is still not interested - keep trying the same at every time you feed her. Sometime giving a little food via tube "jump started" Ducia's appetite and she'd eat a little on her own and then I'd finish it via tube. If that doesn't work - talk to your vet about anti nausea, appy stimulant and antibiotics - if should she be taking them now .
She will do a glucose curve today to see where she is regarding diabetes.
Would you care to post the results? I tested my cat frequently as her lethargy and disinterest worried me a lot and I was working very hard to find good insulin dose for her. Being in high-ish numbers or going too low or too low too fast made my cat to appear drowsy and nauseated - resolved once we got her in to the ok range of BG.
i notice that her stools are quite black
Is it blood?
Blood loss can lead to anemia (my cat had it) and if so it could explains her "old lady" type of behavior. Ducia was acting tired, slept a lot and wasn't interested in much around when she was anemic. All resolved once we got her to gain weight via tube feeding, meds and found insulin dose that kept her in relatively acceptable BG numbers for a while. If Boo bleeds - a vet visit is in order to investigate the reason.
Sometimes after a pate style food my cat's poop looks black - we inspect it for presence of black tar-ish matter and so far it does not seem to be blood. Her poop looks different/lighter when she eats non pate food.
I tube feed her and she sleeps all day and purrs when stroked, but does not seem terribly engaged in anything.
Then it makes you luckier than me - Ducia never purred for me. Never. It's a good sign that Boo does.
How is her weight?
I hope this helps. I really think it is too early to expect any significant improvements. Ask you vet about meds I mentioned above and just keep do what you doing - she'll come around. I think you are doing great job with her and will succeed.
