Black Widow Bites in Cats

Chelsea Hoffman
Black Widow spiders can be icky little pests no matter where you live, especially if you have small children or pets. If you have indoor or outdoor cats you may be worried about them being bitten by a spider. Knowing the signs and results of Black Widow bites on cats is important.

Both the male and female black widow are poisonous. However the female has more venom than the male, and her venom can be fatal to small children and animals, depending on how big the spider is and how many bites are given. Pets like small dogs and cats can die from a Black Widow bite.

Black Widows usually nest in dark secluded places that aren't disturbed often, such as garages, garden sheds, storage bins, and any crevices or cracks in the house or other structures. Ordinarily a pet cat will not disturb such areas, but curious kitties sometimes poke their noses where they do not belong.

The first sign your cat has been bitten by a spider, is that there will be extreme pain in a localized area. If your cat reacts to your touch as if he or she is in excruciating pain, you will want to examine the area.

If the bite is not fresh, hair will begin to fall from the wound in patches. This will expose the spider bite, which will usually be red and swollen.

Almost immediately after being bitten your cat will experience tremors and seizures. These muscle spasms are ordinarily very painful, and will render the cat unable to move much.

Soon after the muscle spasms end the cat will become paralyzed. This is because the Black Widow spider's venom attacks the nervous system, and a small animal like a cat cannot handle the massive dose of venom that the spider packs in it's bite.

A great majority of the time, if a Black Widow spider bite is untreated in cats or other small animals, death will result from it. This can be partly because of the loss of muscle control, which restricts the animal's breathing and other vital functions.
