Note, however, that other veterinary procedures can also require patches of the cat’s hair to be shaved and this is not a foolproof way to check if the cat has been splayed. Many vets spay younger cats using the flank approach. If your cat is young, also check for a square section of clipped or shaved fur over the left side of the cat’s body between it’s ribs and hip.

Usually, the scar will be a straight, thin line running lengthwise in the center of the abdomen. Also look for a scar on the left side of the cat’s body between the rib and hip area. If the veterinarian used a flank approach, the scar will be in this area.

You’ll also want to check the cat’s inner ear for tattoos — this is a common site for important information to be marked on pets. In the US, a letter M means the cat has been micro chipped — almost all other tattoos mean the cat has been spayed. [4] X Research source

A cat in heat will often act very affectionate, rubbing herself against people and inanimate objects and rolling around in a playful frenzy.

When a female cat goes into the crouching position, she will likely also tread or paddle with her back feet. She will lift each back foot quickly, like she is walking in place. This is thought to attract males during heat because this causes the female cat’s genitals to jiggle up and down as she walks.

Other, less-common calls may range from quieter, inquiring mews to agitated screeches.

Keep a close eye on the cat whenever you enter or leave the house. If your cat escapes from the house, she may come home pregnant as she is not spayed.

A cat should be taken to a veterinarian if there is a profuse discharge, as this indicates a womb infection.
