My cat Spooky was diagnosed 1 1/2 years ago with it. Its been quite an
adventure. 2 shots a day, and special food cover the basics. But there are
some serious $$ to consider. the cost per month to "keep her up" is $160.

that's 30 to 40 for needles, 60 for the insulin (9 units twice a day.) 60
to 80 for DM cat food. and then there is also the cost of doctor visits to
keep her blood numbers ok that is every 3 to 6 months and costs between $170
to $500 depending on how many blood curves it takes to find the sweet spot.

 Is it worth it? You bet!

She's 11 years old this year, and still acts A-OK doesn't play much, but is
a total FOOD WHORE! she can hear you take a bite of something from a dead
sleep on the other end of the house with the TV on. She is relentless. I
don't feed her scraps or regular food, but that never stops her from trying
to steal it right off my plate when I turn my head..
 People see her do it and swear she had turned into a dog.

 Good luck with your baby, treat her well, and feed her right and she will
be with you for a long time to come.
