My 14 year old indoor/outdoor cat has been diagnosed with diabetes. I travel for my work, so am unable to provide the twice daily insulin injections. But I did change her diet to all protein. Over the past 3 years she has gotten thinner, slower, and weaker, but still visits for caresses.

Trouble is, she is urinating all over the house. I try to keep the litter box clean, but my husband is ready to feed her to the coyotes. Even my love for her is laced with resentment at this point.

At what point will she be truly suffering with this disease? How long will she live? I have never put down an animal before and prefer not to, but certainly don't want her to suffer.

    I don't know how similar feline diabetes is to human diabetes, but if my mom doesn't get her insulin shots she won't be in pain, but she won't be feeling swell either, she'll feel sick, dizzy and lethargic.

    Your vet can probably answer this question

    Honestly the energy put in by two humans to resent this poor animal could have been better used in treating her condition properly. My diabetic cat ceased urinated constantly when I treated him according to the vet's instructions. He's now in remission after careful care. Since this is a member of your family, it's reasonable to ask your family, friends and spouses to help out. Injections are a lot easier than cleaning cat urine. Best of luck to everyone caring for their dear kitties!

Your cat is showing symptoms that are signs of untreated diabetes in humans at least (weight loss, increased urination, fatigue), and untreated diabetics say the condition is quite uncomfortable. Untreated diabetes can lead to pretty awful complications in humans as well, such as blindness and susceptibility to infection. I'm guessing the same applies to cats. If you are unable to treat your cat, and considering her age, I think you should seriously consider putting her down.


First off speaking as someone that has had type I diabetes for 20 years, pain isn't the most common thing I associate with the disease. It does however cause a great many changes making life unpleasant and has led to secondary problems. Feline diabetes causes similar issues with your cat. Untreated diabetes leads to consistent elevated glucose levels in your cat's body. This will basically cause stress on it's organs. Side effects may include loss of feeling (neuropathy which can be painful as well). It can cause slower healing of the extremities, lead to blindness, circulation issues, kidney failure, ...

If you're unable to provide your cat with the medication it requires you should seriously consider finding someone that is home and able to give your cat treatment and give your cat a new and healthier home. A simple switch to a protein only diet will not "cure" the problem. If you want your cat to live out the remainder of its life as best as best as possible you need to seriously consider these things.

You can read quite a bit about feline diabetes here


Please take your cat to the vet and express your concerns. Ask the vet directly how your cat feels on a day-to-day basis.

  • Is she in pain?
  • Is she uncomfortable?
  • Is her mental state affected?
  • What should you look for to identify pain and altered mental status?

These answers should help you determine when euthanasia is the right time.


I have a diabetic cat as well, and the symptoms you mention are signs of diabetes getting out of control. Nothing to play with. Take her to a vet to get glucose numbers. This can be life and death.


Please treat your cat. Two shots of insulin a day is pretty simple. Testing is also simple. Sure beats urine everywhere. Of course the kitty doesnt feel well. How would you feel if you were sick and had an untreated medical condition? Your husband sounds ignorant and to ignore the real issue here is horrible. Its like blaming someone for throwing up with a stomach virus...ridiculous. Either treat him well or pass this sweetie on to someone who will. It can be overwhelming at first. But it becomes routine. Its a treatable condition and most cats eventually go into remission. Have some compassion. Euthanasia is not the answer here either. Responsiblility and compassion, education and lack of ignorance is the resolution.

    If insulin is not working then you either need a different dose, or insulin type. There are many facebook groups for feline diabetes support. Feline diabetes support group is where you will find help for your kitty
