Hi Kate,

Keeping them out of each other's food can be tough. If you can do it,
serve the cats' meals at a specific time. Isolate the diabetic one from
the others while eating.

Wet food was recommended for our diabetic cat. If you are using dry and
free-feed, could you leave the diabetic dry out for everyone? Our cat
was pretty good about staying away from the other's dry food because he
had his fill of wet food. You could also serve them wet meals, but leave
a little diabetic dry out to nibble on during the day. Our vet wanted at
least some food out in case Bob's sugar went to low and he needed to eat
while we weren't there.

You can do bloodtests at home, using glucometers that you get at a drug
store. There's a great message board that helped me with all of my
diabetic cat questions here:

They are experienced in every aspect of taking care of a diabetic cat.
They will have websites about blood testing, etc.

Good luck,

Rhonda
