Hi Amy,
Here is some info on low blood glucose symptoms from the 'How to treat hypos' sticky (the link to the page follows this extract):
SYMPTOMS
Some cats may have NO symptoms whatsoever, but here are the most common ones:
MILD HYPOGLYCEMIA
Sudden ravenous hunger
Shivering
Weak or lethargic
MODERATE HYPOGLYCEMIA
Disorientation
Trouble with vision... bumps into furniture
Poor coordination, such as staggering, walking in circles or acting drunk
Changes in head or neck movements
Restlessness
Urgent meowing
Behavioral changes, such as aggressiveness
SEVERE HYPOGLYCEMIA
Convulsions or seizures
Unconsciousness

In addition to the above other symptoms include dilated pupils, and cats either going into cupboards or other small spaces, or sitting staring into the corner of a room.
Be aware that the
symptoms don't always follow a progression from mild to severe: Some cats show symptoms early on, some when the hypo is moderately advanced, and some only show symptoms when the hypo is severe.
For example, some folks here have noticed that their cat suddenly gets really hungry
(mild). My cat has had 3 hypos and his symptoms have included dilated pupils, disorientation (swatting at something that wasn't there), staggering and falling over, and aggression
(moderate). And another member here had a cat who was fine one moment (sitting with her on the sofa watching TV) and then it had a seizure
(severe).
I hope the above doesn't alarm you too much. Many, many cats never suffer from hypo.
In terms of
hyper symptoms, well, all newly diagnosed diabetics are hyperglycemic.
The commonest symptoms are the symptoms of diabetes itself; drinking and peeing a lot (and possibly UTI's), poor coat condition and dandruff, and weight loss. Some cats seem to feel unwell at high numbers. But many cats get used to the high blood glucose levels (which can sometimes be problematic when trying to get their blood glucose levels down again!)
Ketones can be a major concern at high numbers (and even sometimes at not so high numbers). Some cats seem to be ketone-prone, and if this is the case it is important to monitor the cat's urine for ketones (or even get a blood ketone monitor). Ketones are particularly problematic if the cat is off it's food and unwell, as DKA is more likely to develop.
Ketodiastix test strips test for both ketones
and glucose. Regarding glucose, the test strips will only show you how much glucose has spilled into the urine since the cat last had a pee, but, in the absence of other information this may still be useful to know.
