In our 6th week of tube feeding, and no end in sight

I have to admit that it feels like we've been pushing food through a tube into Mack's stomach for EVER. I counted the weeks -- on Thursday, we'll have completed 6 weeks, and he's still not consistently eating enough food on his own to sustain himself.

What is more disturbing is that he doesn't seem to care much.

He doesn't eat MORE food if we push LESS through the tube. He doesn't eat LESS food if we push MORE through the tube. He doesn't eat more if we push more; he doesn't eat less if we push less.

There seems to be absolutely no correlation between the two at all.

He doesn't even eat more if I give him the appetite stimulant than when I leave it out of his diet.

And he isn't interested in ANYthing but Kitten Chow. Not liver pate (Hill's Prescription Diet a/d). Not Fancy Feast Liver Feast (which his brothers would KILL for). Certainly not the everyday Purina urinary health food the other boys are eating.

I don't want to rush him, but ... I'm not sure he is moving ON, if you know what I mean.

I'm also getting a little worried about the condition of the site where the tube goes into his throat. He's been scratching at it more, and it seems a little exposed and crusty. I don't know how long it can be okay to have an open wound like that.

Tomorrow, I'll call the vet.
