If a fresh needle is used every day, the cat will hardly feel it, and often a cat will get used to the routine and may even wait patiently for the shot after feeding. Accompany the injection with lots of affection and sweet-talk, and the cat should see it as a pleasant experience. The owner can decide which times are best for feeding and dosage. It does not matter, as long as they are at the correct interval. Once this routine is established, the cat should be returned to the vet for a blood glucose test every three months.
Many owners choose to test their pets at home using human diabetic test kits.
This allows for a more accurate determination of how the dosage is affecting the cat, but usually isn't necessary. It is usually done by drawing blood in the cat's ear. Occasionally, cats go into remission and no longer need insulin. There may also be times when the cat does not eat enough, or vomits, and the usual dose of insulin will be too high. Just like humans, cats can go into insulin shock and possibly die if untreated.
