I noticed your post about giving fluids to Natasha, and forwarded it to
my daughter, who had a cat who needed daily infusions.  Following are
her suggestions:

Probably the most important things are to remain calm and act as if the
whole process is no bigger deal than combing for fleas, and warm the
fluids
to "tepid" before administering (the shock of injecting cold fluid or
too
hot fluid can be very stressful).  Also, small gauge needles (21 or 22
gauge) seem to hurt much less than the typical 18-gauge that the vets
give
out with the fluids.  The flow is slightly slower, but it's definitely
worth it.

Here are a few links with tips:

I hope Natasha does well with this one-week regimen and doesn't need to
have this on an ongoing basis.  If it turns out she does, however, I
strongly recommend the Feline CRF Support Group (on Yahoo groups).  Let
me
know if you need more info.
