If your cat is having either sedation or a general anesthetic then she needs to be starved for at least 12 hours before the surgery.


This is because when asleep under anesthetic the cat loses the ability to swallow.Thus if the sphincter (valve) guarding the entrance to the stomach relaxes under anesthetic, the pet may vomit whilst asleep and breathe in the vomit at the back of her throat.
This is highly likely to cause a serious pneumonia and is entirely avoidable by making sure her stomach is empty prior to the procedure.;
, If the cat is being admitted the following morning, all food must be removed at bedtime (10-11 pm) the night before.


It is fine to let her have access to drinking water overnight, but you should also take this away at breakfast time (7 am) the day of surgery.
 Taking food away sounds simple – you just pick up the bowl and make sure no one else in the family feeds the pet by mistake – but in practice it can be more complicated than this.


For instance, in a multi-cat household your options are to starve all the cats in the house for one night, or to confine the cat going for surgery to one room and give her a litter tray.
If you think the cat will become stressed if she is not allowed free range of the home, consider asking the vet if she can be dropped at the clinic the night before.
She may well settle there just fine, because she is wrong-footed by not being on home territory. It also means she is not traveling on the day of surgery and may be happier for this.
 A hungry cat is a convincing cat when it comes to persuading people to feed her. Also,remember to keep the cat indoors so she can't go and beg from neighbors.
 It is a good idea to lock the cat flap overnight. It is a story familiar to many veterinarians that the cat disappeared out through the flap on the morning of the op.


Make sure all family members know why the flap is locked, so that no-one falls sucker to a mournful cry from a bewildered puss first thing in the morning.
Other factors include whether the cat hunts or not. If she is likely to go and hunt down her own supper then she must be kept indoors overnight so this cannot happen.
In a multi-cat household, again, this may require preventing all the cats from going outside. If this is impossible then speak to the vet clinic and see if it is possible to drop the cat off the night before, to stay in a hospital bed.
Although the one cat may not be best pleased, at least it prevents the rest of the household's cats from becoming stressed.
 Where possible, prepare the cat carrier the night before (or even earlier than this). This allows you to check if it is serviceable and gives you time to make any repairs to broken straps or hinges in time for the morning when it is needed.
 Plan to remove water first thing, about 7 am. Water passes out of the stomach much more quickly than food and does not pose the same risk if removed 2 to 3 hours beforehand.


There is no advantage to taking away water the night before, indeed this is not advisable because the cat may go to surgery slightly dehydrated and this can decrease the blood supply to her kidneys and cause damage.
 Not all cats travel well so prepare for "accidents" and line the bottom of the carrier with absorbent material such as a puppy pad or newspaper.


Put bedding or a T-shirt in the carrier for the cat to snuggle up to. It helps if the bedding has a familiar, comforting smell such as a piece of clothing that belongs to you.
 Feliway is a synthetic version of the feline pheromone that makes kittens feel safe and secure. It is available as a room diffuser, or a spray for pet bedding.


When breathed in it gradually reassures the cat and gives her the message that this is a safe place and there is nothing to worry about.
Consider spritzing the bedding with Feliway prior to travel to try to decrease the cat's stress levels.
 Ideally, leave the carrier out for weeks before hand, as an inviting den to sleep in. However, failing this you may need to insert the cat into the box, which can be tricky.


The element of surprise works well. Have the carrier door open in preparation, pick the cat up and swiftly place her into the box and close the door. However, once the cat is forewarned she is more likely to resist.
Some cats object to going in head first, because they perceive they are being forced into a dark place. Try inserting them bottom first. To do this, if you are right-handed, thread your left arm under the cat's belly so her head is near your elbow and her tail near your hand.
Gently grasp both back legs in your left hand, so that she can't splay her legs out, and put her into the box backwards (for a front opening box). This works well for the majority of cats.
 Secure the cat carrier into the car by looping the seat belt through the handle and anchoring it. Know the route you need to take to get to the clinic, and allow extra time for school traffic and the like. Better to arrive early and calm than late and stressed, as the cat will pick up on your anxiety.
 If your cat is on medication, either long-term medication such as pain relief, or short-term such as antibiotics, ask your veterinarian whether the medication should be given or withheld on the morning of the surgery.
 Some medications such as non-steroidal anti-inflammatory pain killers, e.g. metacam, must not be given on an empty stomach. Thus they should never be given on the morning of surgery because the animal needs to be starved.


However, these drugs are often effective for 24 hours so if the cat had a dose the previous evening, tell the veterinarian.
This is important because pain relief is a big part of modern anesthesia and many clinics routinely give a pain relieving injection as part of the pre-med protocol.
Your clinic is highly likely to be aware your cat is on meds, but it does no harm to reinforce this since an extra dose could have harmful side effects.
 If, for example, the cat is due an antibiotic on the morning of the surgery, alert the clinic that she has not had the tablet. This allows them to give that day's dose by injection, if necessary.
 If your diabetic cat is due for surgery, the clinic should give you clear instructions about what to do about insulin and food on the morning of the procedure.


Water: Leave water down right up until you put the cat in the basket. Diabetic cats need to drink more and if deprived of water quickly become dehydrated. Dehydration puts a greater strain on the kidneys. In fact, once at the clinic many veterinarians will put a diabetic cat on an intravenous drip to keep them stable whilst water is not allowed by mouth.
Food: The same rules about starving apply to diabetic, as well as non-diabetic animals. No food from 10-11 pm the previous night.
Insulin: If your cat is on twice daily insulin injections, the morning dose of insulin is reduced by half. For example, if the regular morning dose is 4 units, you give 2 units, because she has not eaten and her requirement for insulin is reduced.
If you give no insulin at all there is a risk of ketones forming as a result of her blood glucose levels climbing. A half dose is unlikely to reduce her blood glucose to dangerously low levels, and is enough to prevent ketone formation. If in doubt, always speak to your veterinarian about the dose.
 The clinic will ask for a contact phone number. Make sure that you are fully available at all times on that contact number.


The vet may need to speak to you about something simple like if it's okay to implant an ID chip, or it could important information such as a discovery made during surgical investigation.
If the vet cannot reach you, he won't be able to act. If you are not contactable, the vet will not have consent for any procedures not covered on the consent form.
This could mean the cat has to wake up, only to need another anesthetic at a later date for a procedure that could have been sorted out there and then.
