Pre-Purchase Considerations For Cat Flea Shampoo

Here are some factors to take into consideration when shopping for flea shampoo for your cat.

1. Effective, Natural Ingredients

An effective cat flea shampoo does not need to contain harsh chemicals that could potentially hurt your cat. Unfortunately, there are flea shampoos for cats on the market that include chemicals that are not safe for cats. Look for products with natural ingredients, and make sure you read ALL the ingredients in a flea shampoo before you buy.

2. Soothing Ingredients

Cats often end up with inflamed, irritated skin after a flea bath. A good flea shampoo will include natural soothing ingredients, such as Aloe Vera, coconut oil, and lanolin, to rejuvenate your cat’s skin. 

3. Preventative Benefits

You want a flea shampoo that not only kills existing fleas but future flea infestations. Also, keep in mind that many flea shampoos target other parasites, such as ticks, lice, and even mosquitos. Choose a shampoo for cats that works as a preventative, and a flea spray in and outside your house to kill and repel fleas. 

4. Number of Baths Necessary for Maximum Treatment

Some flea shampoos only require one bath for maximum effectiveness, while others require more. Obviously, most cats aren’t going to enjoy baths at all, so the fewer flea baths, the better.

5. Fresh Scent

Just because it’s in shampoo form doesn’t mean it smells good! Look for cat flea shampoos that smell good. Reading customer reviews helps, too.

Frequently Asked Questions

What are the signs that my cat has fleas?

Flea bites are painful and itchy, so if your cat has fleas, she will show symptoms of scratching and biting her skin, and she may develop a rash.

You may notice her grooming herself more. If you look closely at your cat’s coat and skin, you may see fleas. They could be anywhere on her body, but flea hot spots include the neck, lower back, hind legs, and tail.

Does flea shampoo for cats work on ticks, too?

Flea shampoo for cats is designed to kill both fleas and ticks. As you have seen in our top five recommendations, some flea shampoo for cats will also work on eggs, larvae, and lice. It’s important to read the flea and tick shampoo labels to know exactly which parasites are targeted. 

My cat hates water; how do I give him a flea bath?

Most cats don’t like water, so giving your cat a flea bath may be a strenuous task, but it is necessary if he has fleas. You may need to enlist someone to help you if your cat is especially resistant. Make sure you are as calm as possible throughout this process, as your cat will sense your energy.

First, trim your cat’s claws a day or two before bathing. Right before bathing, brush her coat to ensure there are no knots and tangles where fleas are hiding. Fill the bathtub with warm water, around eight inches high. Gently place your cat in the water and let her get used to the temperature. Use a large cup or something similar to rinse your cat.

Then, apply the cat flea shampoo and spread it throughout her skin, avoiding her eyes. Some people have found that using a cat brush during this step is also effective. Let the flea shampoo sit on her skin for a few minutes, and then using the cup, gently rinse the shampoo from your cat’s fur and skin. Use dry towels to dry your cat, and after she is dry, use a flea comb to remove any additional eggs, larvae, and adult fleas.

How do I prevent flea re-infestation after I give my cat a flea bath?

When it comes to eliminating fleas for good, you should rely on more than a flea bath. Once your home is infested, fleas may keep coming back.

Your best bet is to talk to your veterinarian about your best course flea treatment. Mild fleas can be controlled with flea baths and treating the area with a quality flea spray. Let’s be honest, though; fleas multiply rapidly. A female flea can lay up to 50 eggs a day, so you may need to have more flea control methods in your plan.

There are other forms of flea treatment, such as topical and internal medications for your cat that your vegetarian can recommend. In addition, it’s a good idea to vacuum your home every day, including furniture and wash bedding, sofa covers, and other fabrics your cat has touched at least once a week. Use hot water in the washing cycle.
