MAGIC is probaby the world’s biggest domestic cat. She is certified by the Guinness World Records as the tallest (20-9-09). Watch this space for an update to world’s largest.

Here is another video of Scarlett’s Magic. This shows her size very well too:

Method

The research needed to build this page automatically resulted in finding the smallest domestic cat breed as all the cat breeds are included in the research (although at present only a few are not listed). In fact, in compiling a list of the largest domestic cat breeds you will have to research all the weights of all the breeds. And I am talking weights rather than physical size; meaning physical dimensions. This is because research of domestic cat size nearly always refers to weight and weight is directly related to cat size. The two go hand in hand, provided the weights used are typical.

This page therefore looks at the weights of all cat breeds and cats that are not formally a breed because a cat association has not yet (or never will) recognized the cat. As it is interesting to compare domestic with wild cat, I have also included a comparison to some small and medium sized wild cats.

One of several obstacles is the question as to whether I should adhere strictly to the title of this posting. Should I only look at cat breeds that are formally recognized to full status by the premier cat associations or make the “competition” open and compare all cat breeds. I chose the latter because some of the breeds that are not recognized by all the associations but which are established nonetheless, are interesting, big and it is easy to include them. I set out the largest domestic cat breeds by association at the end plus the breeds that are the largest whether they are recognized or not (the equivalent of “open competition”).

However, in order to remain loyal to the title I have made a note in the table as to which associations recognize the breed.

I have selected the following associations as the major players and upon which I have decided if a cat is formally a breed or not. If the cat is listed on their websites as recognized, I treat that cat as a breed for the purposes of this analysis:-

  1. Cat Fanciers Association (No.1 in USA and biggest in world)
  2. The International Cat Association (No.2 in the USA and international)
  3. General Council of the Cat Fancy (UK)
  4. Fédération Internationale Féline (this includes Europe and Brazil)

Internet research requires extreme caution as the information is often obtained in a circular fashion, meaning one website copies from another and so on. If the first site is incorrect, they are all then incorrect. Accordingly, I always treat information with caution, always look for authoritative information as the prime source and then test it against other sources to create fresh information on the largest domestic cat breed.

Where I have had to make an informed estimate, I have limited the information provided to the minimum required to answer the question posed. Full descriptions of all the breeds in the list are on this website. Go to the home page or navbar for a list of links.

one of the largest domestic cats

The serval (picture above) is a wildcat that is sometimes tamed to become a domestic cat and that is why this cat species is in this analysis. This cat is not a “breed” but a species. It is not the largest domestic cat breed but is one of the largest domestic cats when tamed. Photo is of Martin Stucki with a tame breeding serval at A1 Savannahs, OK, USA. See tame and socialised serval cat as well.

Table – largest domestic cat breed

Largest Domestic Cat Breed – Table – showing cat breed minimum, average and maximum weights in both pounds and kilograms. The figures for large cats are not meant to be maximums as you will get an exceptional cat but that does not answer the question as to the Largest domestic cat breed. Please note that these are average figures so they are an amalgam of male and female weights.

Also things change (getting heavier I suspect) and different cat breeders or cat associations may have different ideas about cat breed weights.

Update: I have included weights from The Encyclopedia of the Cat by Dr Bruce Fogle as at May 2010.

As a guide average sized male cats should weigh in the order of 9-12 pounds and females about 7-9 lbs (although this can be challenged!).

Both pounds and kilograms shown.

  1. Allerca is effectively a mixed breed cat in terms of cat breed and the cat’s weight is decided accordingly
  2. Ashera GD is effectively a Savannah, a wildcat/domestic cat hybrid. The weight has been assessed accordingly as an estimated weight of an F1 (first generation from the wild Serval) Savannah. This cat is not a breed recognized by the cat associations but this is a domestic cat and I include it on that basis. If the Ashera GD is a Savannah in all but name that supports the view that the cat should be included in this survey. Update: it is a Savannah cat.
  3. When this cat is a domestic cat, he or she is a tamed wildcat. She is firmly in that twilight zone between wild and domestic cat and the cat associations do not recognize her as a domestic cat breed. However, as the situation stands, she is treated as a domestic cat breed for the very few people who have the means and desire to keep this beautiful wildcat. This breed is therefore included in this survey on the largest domestic cat breed.

Note: Miniature cats are not cat breeds neither are Teacup cats. These are mixed breed cats, bred small. They cannot therefore form part of this list.

One undeniable fact is that the vast majority of domestic cat breeds are medium sized cats. Within the ranks of medium sized cats there is some variation in size and weight and it is this that I have tried to ascertain and set out in the table. There are one or two outstanding cats in terms of size at the heavy end of the spectrum. At the light end the situation is less clear.

Without wishing to overstate the obvious this page does not provide the results of research into the largest domestic (individual) cat. But in order to respond to some visitors who might have arrived here looking for information on that subject, here is some.

Stories will pop up from time to time about exceptionally large cats. One is in the papers this morning (11-4-08). It concerns a ginger mixed breed cat called Orazi. I can’t show the picture due to copyright issues but he is basically a very big cat anyway and he is overweight. That is why he weighs 35 lbs (16 kg)! He is Italian. Maybe he eats too much pasta.

Other record breakers are Sam a British cat weighing 36 lbs (16.3 Kg). He was a fat cat proving the point that individual records are pretty meaningless except to say the people keeping thes cats are overfeeding them. An American cat weighed 41 lbs (18.5 kg) apparently. See also: World’s Fattest Cat and Clauz World’s Fattest Cat 1950 and World’s Biggest Cat.
