Do you mind if I ask what type of procedure was used to remove the tail.
A recipie for tube feeding that's worked on some sav's here is:
Hissing cockroaches
Lg crickets,
pinkie or fuzzie mice
egg
Calcium glucanate
Vit D3
all nice and blended in a blender.
Just a suggestion It has worked wonders with some of our rescues.
Oh PS don't drink margaritas at our house, you'll notice we only own one blender..lol
