FAQ:

Q: What is the best natural flea treatment for cats?

A: Hydrogen Peroxide is another effective natural flea treatment for cats. By applying this to a cat’s fur, fleas will begin to die immediately and drop off. This is best done in a bathtub where the cat can be rinsed off after you’ve finished treating them.

Q: What are the best flea pills for cats?

A: Sentry Capguard Tablets has the same active ingredient as Capstar and the three other best flea pills for dogs we’ve named so far. Capguard interrupts flea infestation by killing adult fleas on your pet’s body. Pets must weigh at least 2 pounds and be at least 4 weeks old to be safely given this medication.

Q: What is the best tick medication for cats?

A: A flea collar with flumethrin and imidacloprid (Seresto) can also work well. Medicines your cat eats. The pill nitenpyram (Capstar) kills adult fleas on your cat within 30 minutes. It doesn’t have any lasting effects, though. Spinosad (Comfortis) is a fast-acting chewable that starts killing fleas before they lay eggs.

Q: Can flea medicine kill a cat?

A: A quality flea medicine for cats will aid in the elimination of fleas through its active ingredient. The medication is excreted through the cat’s skin, and once a flea bites it, the flea becomes paralyzed resulting in death. Some medications kill adult fleas only while others can also kill flea larvae.
