What to Consider
When Choosing Flea Medicine

By now, you should know that choosing flea drops is important. But, how can you pick the right one for your pet?

1. Toxicity Level

One thing should be clear when you are looking for flea medicine not just for flea drops, never use a dog’s flea control medicine on your cat. Remember that cats and dogs are both mammals but their physiology is entirely different. You need to consider this since treatment that is safe for canines may turn out to be toxic to your cats.

Aside from that, you should also read what is on the label. This may seem to be the first thing that you should absolutely do but there are some people who don’t do this too often. Make sure that the ingredients are all safe for your felines before proceeding any further.

2. Type of cat

Where does your cat live? You may have an indoor cat or an outdoor cat. Of the two outdoor cats are more prone to flea infestation.

If it is an outdoor cat, you need to make sure that you give the cat treatment for fleas on a regular basis since they are more prone to having these parasites. Although it doesn’t mean that indoor cats are exempted, the chances that they will have fleas are definitely lower than your outdoor cats.

3. Application

There are some flea drops that are recommended for cats up to a certain weight. This is a unique consideration and you need to read the labels to see if your cat’s weight will qualify. This consideration is dependent on the type of cat that you have, so it only makes sense that you won’t buy a flea drop that is for cats up to 10 lbs. when your feline is 14 lbs.
