My 14-year-old (will be 15 on April 8), Bandit, just went in for a dental
cleaning today. She had just had a geriatric exam on December 12 and her
creatinine and BUN have gone up since then (the vet said she is not
concentrating her urine as well as when she was younger). I'm worried that
these is (to me) a big jump in creatinine and BUN and that it is too high,
but the vet said these figures are normal for her age (and none of my cats
have ever been ill - Bandit is the oldest, so I know *NOTHING* about these
things).

To give anyone who is informed enough information, I'll post all her lab
results in case there are other things that need to be factored in, then ask
my question at the bottom of this post.

OK, I need this tranlated into vet lab results for dummies 101 (Phil,
Kristi??). Seriously, I don't know from Adam, but it seems like that is a
pretty big jump in creatinine and BUN values in just a little over 2 months.
Am I wrong to be worried?

When Bandit got her results in December the vet told me to start her on SD
canned (she's had SD dry all her life and no problems before this). At the
same time I got a Drinkwell fountain for her to encourage her to drink.

Do you think she should be on a prescription diet?

BTW, her teeth and gums were fine, just needed a good cleaning since it's
been about 3 - 4 years since the last time she had it done.

Any advice or opinions are gratefully welcomed.

Hugs,
