Spay or neuter surgeries are one of the most common procedures given to cats and dogs by their owners. Theyâre also one of the most responsible ways to care for your animal.
First-time cat and dog owners often have a lot of questions about the process, especially when it comes to the cost, whether itâs truly beneficial and how to care for them post-procedure (tip: a VetBed will come in handy, and you may also need an inflatable collar).
Here is a definitive guide to the procedures, and why getting one might well be the best thing you ever do for your pet.
Spaying vs. Neutering: Whatâs the difference?
Whether youâre looking to spay or neuter your pet depends entirely on their sex.- Spaying is the removal of a female animalâs reproductive organs
- Neutering is the name of the procedure for male pets
Reasons to spay or neuter your pet
Spaying and neutering are very common, and the benefits go way beyond preventing unwanted offspring.-
Health benefits
Fights disease
Spaying a female cat or dog can better prevent uterine and breast cancers, which are fatal in 90% of cats and 50% of dogs. Similarly, neutering is the best course of preventing testicular cancer in your male pet.Limits fighting and aggressiveness
Cat mating is not pretty and can result in injuries such as biting and scratching. Unneutered male cats are often violent towards females when mating, so it is good to neuter males to prevent this as well as spaying females to limit the attempts of males trying to breed with your female. Unneutered and unspayed male and female cats can also be aggressive because of protecting their territory. An unneutered male who has FIV (Feline Aids) can spread the disease through biting when fighting. A neutered cat is less likely to fight or be targeted.Ends their heat cycle
Spaying will also end a female cat or dogâs heat cycle, which is often a very stressful time for your animal. While dogs go into heat no more than three times a year, cats often go into heat much more due to their six month mating season. This can mean plenty of spikes in unwanted behaviour such as yowling for mates, frequent urination and sometimes aggressive behaviour, which spaying will help put a stop too.-
Behaviour benefits
Stops pets roaming away from home
While cat owners are used to their felines far roaming activities, dog owners might be surprised to find an unneutered dog will roam even further to find potential mates. If they can find a way to escape your home, they will, increasing their risk of injury on busy roads. This could be dangerous if you take them on walks and they are off the lead particularly. For cats, they may not return home for hours, causing a lot of worries.Ends aggressive behaviour
The general behaviour of a male animal will also improve remarkably as their focus becomes not on mating, but interacting with their family. Unneutered dogs and cats often suffer from aggression problems, especially when coming across other males. Unlucky owners may also have to deal with them marking their territory with strong-smelling urine around the home.

Cost and ethical benefits
Ends overpopulation
One of the best things about spaying and neutering your pet is that it helps fight against animal overpopulation. In just six years, one unspayed dog and her offspring can produce 67,000 puppies, while in seven years an unspayed cat and her offspring can produce an unbelievable 370,000 kittens in the worst-case scenario. These numbers are the reason why every year millions of cats and dogs end up unwanted in animal shelters or worse, euthanised as strays. Unwanted stray animals often have negative effects on wildlife, damage local fauna and can even cause car accidents. Spaying or neutering your animal stops the production of over-sized litters, and therefore reduces the number of animals on the streets.Saves money
Not only are you helping save your community by spaying or neutering a pet, but youâre also saving yourself some money too! The cost of one spay/neuter surgery is far less than the stress and price of caring for a new litter. An unneutered animal is also more prone to some illnesses which could be costly to treat.When should I neuter or spay my pet?
It is recommended that females cats and dogs be spayed before their first heat cycle to help best prevent against reproductive diseases later in life. However, you should always talk to your veterinarian to determine the best time for your individual pet. Some may recommend leaving it until after their first season. You cannot spay a bitch while she is in heat due to the increased risk of bleeding. The surgery can be performed after around 2-3 months. Cats are generally spayed or neutered between four and six months. This is the responsibility of the owner if they have adopted the cat as a kitten. Surgery is often performed in animal shelters before rehoming if you go through a rescue. Itâs also possible to spay a female cat while sheâs in heat so donât worry if theyâve already started their cycle. While the traditional age for neutering dogs is four to six months, puppies as young as two months old can be neutered as long as theyâre healthy. Neutering or spaying is a procedure that can also be done later in life for adult pets. But while generally safe, there is a higher risk of post-operative complications.Cost of spaying or neutering
The average cost for neutering a male cat is ÂŁ30-ÂŁ40 while spaying a female is ÂŁ50-ÂŁ60. To get the most accurate price, talk to the vet who will most likely be performing the procedure for your pet. Unfortunately for dog owners, the price can vary depending on the size and breed of your pet. On average, the cost for neutering a male dog can be anywhere between ÂŁ110 to ÂŁ300, while spaying a female ranges between ÂŁ130 to ÂŁ365. Prices range so heavily due to the varying sizes of dog. Larger dogs need more anaesthetic and surgery often takes slightly longer than with smaller breeds.
Most vets will often split their prices into weight bands, so you can expect to pay the lower end of the spectrum if your dog is under 10kg, and the higher end if your dog is over 50kg.
Spaying is more expensive than neutering for both dogs and cats due to the operation being a more complicated surgery, as it involves the removal of internal organs.
If youâre worried about the costs, many charities can offer subsidised or discounted neutering schemes based on means-tested benefits.Contact the trusts below to see if youâre eligible: https://www.dogstrust.org.uk https://www.cats.org.uk Most rescue centres will also carry out the procedure as a given, and the adoption fee goes towards this.
