I also found it very difficult to understand your post, but I will try to offer some small advice on your problem.

I am really sorry that Trixie is making things difficult for Katr. Is there any way you could keep them in separate parts of the house? Or at lease feed Katr in a separate room to make sure she gets enough to eat, as you said that Trixie chases her away from the food? The only other thing I can suggest is that you keep Trixie's claws trimmed so she can't hurt Katr as badly when she scratches.

Guys if anyone else can give prettykitty1 some advice I will try to sumarise her post:

Approx 1 year ago they rescued Trixie - who turned out to be pregnant.

Trixie's kittens were re-homed with family members.

Now due to changed family circumstances, Katr (kitten) and Trixie (Mommy cat) are living in the same house again.

Trixie chases Katr out of the house and drives her away from the food bowls.

Katr is now living in a hole under the house

Anyone have any ideas?
