Bed bug bites on cats or dogs can cause acute skin irritation, pink welts or spots on the skin, intense itching and even allergic dermatitis. If your pet is losing a great deal of hair, and if it is not from ticks, fleas or usual shedding reasons, then there is a possibility you are having bed bugs in the home.
Although it is typically uncommon for bed bugs to make their way onto your pet while it's outside — after all, bed bugs are nocturnal and they don't particularly like fur — for the safety of your pet and your family, you shouldn't disregard the possibility.
Humans, cats, and dogs can be bitten by the parasites, but none of us carry them on our bodies. Bed bug bites can cause itching and may exacerbate allergies in dogs and cats. Bed bugs can infest your pet's bedding just like they can infest your bedding. If this happens, do not apply pesticides to your pet's bed.
If bites are present, consult your veterinarian for treatment options; over-the-counter bed bug shampoos meant for dogs may be harmful to cats. Beds and Toys Because bed bugs are small and easily spread throughout a home, treat your pet's bedding and toys in a similar manner to your own bedding.
With pets, you are more likely to find the bugs in carriers or crates, bedding, toys or other items close to where the pet sleeps. If you're petting your cat while you are on your sofa and spot a bed bug on the cat, check the sofa — not the cat or the cat's area of sleep. Chances are the sofa is infested.
