Why Do Pets Need to Fast Before Surgery? Pets need to fast before surgery to prevent vomiting and aspiration during anaesthesia, which is fatal. Even eating or drinking small amounts during the fasting period can be dangerous, so it's essential your pet doesn't eat or drink before their surgery.
Stop Food. Your pet will need to stop eating prior to surgery. If your dog or cat eats prior to surgery then vomits, stomach contents can travel to the lungs and cause infections, pneumonia or respiratory distress syndrome.
Your veterinarian will give you clear instructions for your pet's diet plan before surgery. The norm is to fast 12 hours beforehand, but there are a few exceptions. Puppies and kittens will be allowed a small meal to give them the energy to go through with the procedure.
For healthy adult cats about to undergo an operation, the American Animal Hospital Association now recommends a 4- to 6-hour fast prior to anesthesia.
Whenever possible, pet owners should ensure that their cat has no food after midnight before a scheduled surgery; however, allowing the cat to drink water will generally be fine.
Most veterinarians recommend no food or water after midnight. This is very important. If your cat eats or drinks right before surgery, make sure you tell your veterinarian.
Pre-operative Care
All animals must have food and water withdrawn the night before surgery at 12:00 midnight. Animals must be in good health, so if your pet is showing any signs of illness such as coughing, sneezing, runny eyes, or diarrhea, it is possible that they will be declined for surgery.
Even eating or drinking small amounts during the fasting period can be dangerous, so it's essential your pet doesn't eat or drink before their surgery. Vomiting, particularly Gastroesophageal Reflux (GER) or regurgitation, is possible during surgery.
If your cat is not consuming water either through drinking or their diet, reach out to your primary care veterinarian or an emergency veterinarian as soon as possible to rule out any more serious conditions. They may also recommend hospitalization to help with hydration.
If your pet seems hungry, you can offer small amounts of food but we recommend not encouraging them to eat their entire regular dinner. The effects of the anesthesia will be minimal at most and usually nonexistent by the next morning. If your pet does eat or drink too much, he or she may vomit.
Regardless of the surgery, you'll need to keep your cat inside for their post-op recovery period. And even indoor cats have to avoid running and jumping in order to have a trouble-free recovery.
Looking after your cat
Generally, following an anaesthetic, cats will take up to 48 hours before they are back to normal. Most of this time will be spent sleeping so make sure your cat's bed is placed in a warm, draught-free place where she won't be disturbed.
Any time a cat undergoes a surgical procedure, there is trauma to the tissues, and pain relief is a critical element of the healing process. The specific medications used for at-home aftercare will depend on the nature of the surgery and the decision of your veterinarian.
Fast your cat the night before surgery. Remove food from where it is usually located, so they do not try to eat it. Continue to allow your cat to drink water until it is time to leave for the surgery. Continue to give your cat any prescribed medications unless we tell you otherwise.
You will need to withhold food for at least 8 to 10 hours before surgery. Water can be left down for your cat until the morning of surgery. Will my cat have stitches?
o Many cats will not have a bowel movement for the first 3-4 days after surgery. o Reasons that a cat will not have a regular bowel movement after surgery include: - Your cat has been fasted prior to surgery. - Your cat may not have eaten well during their hospital stay or the first few days home.
Your cat will probably not drink much either, because s/he will be well hydrated from the IV fluids. Many cats hide, which indicates they are not feeling 100%. Give them time. Most cats need a few days at home convalescing before they begin to act better.
Keep the incision dry for at least 7 days after surgery. The stitches will dissolve over time (unless otherwise stated) and getting them wet will cause the stitches to dissolve too quickly.
Don't try to pet or play with your cat immediately after surgery. While this may feel reassuring to you, it may just keep your cat from feeling safe and rested. Avoid lifting your cat unless it's absolutely necessary. You can easily tear your cat's surgical incision if you lift or move your cat too much.
Yet they still need water and can't survive longer than two or three days without access to it. "Once about 24 hours pass without water, dehydration sets in," she says. "The longer this goes on, the more stress and strain is placed on their internal organs, leading eventually to failure and death."
Some operations require pets to have an empty stomach. You may need to stop your cat from eating or drinking for twelve or even twenty-four hours before surgery. Our veterinarian will confirm this for you. It is important to stick to these instructions to ensure your cat experiences no complications during surgery.
Your vet will likely recommend limiting your pet's movement for a specified period (usually a week) after surgery. Sudden jumping or stretching can disrupt the healing process and may even cause the incision to reopen.
After the surgery, pets are supposed to be confined overnight with limited activity. They should only be walked to go to the bathroom. Some owners will let their animals run around or even roam off-leash outdoors, which can dirty the incision site.
