We have a new kitten - around 8 weeks old.

She was eating and playing the first day we got her home but just sat
around the next day.  That was Tuesday.

We took her to the vet from the cat home where we got her, after our
vet wanted to put her on an IV for fluids and do blood tests, which we
just can’t afford at the moment  (we've just spent out big on
our 2 older cats).

Her temperature and heart rate were normal but she was slightly
dehydrated. No discharge from her eyes, ears etc and her faeces are
only slightly soft.  Her gums were fine, no ulcers etc. The vet gave
us some low grade antibiotics, some Nutrigel (high calorie food
supplement) and got us to carefully feed her water with a syringe.
She perked up and for the next couple of days ate and played well.

Then this morning, she wasn't as interested in her food again and just
seemed to be licking at it.

We are reluctant to take her to our own vet yet as we’re sure
they’ll just says we need to do blood tests.

Does this sound like she may just have some sort of stomach upset
(which is what the cat’s home vet thought – as they
don’t get fed the best quality food in there) or the start of
something more serious?

Thanks for any help
