If you have a cat and like to garden, you might want to use your cat’s poop as fertilizer in your flower beds. In the end, plants can use the nitrogen, phosphorus, potassium, and organic matter in pet waste. However, fresh cat feces also poses some serious risks. This article will talk about the pros and cons of using cat poop to fertilize flowers, including the possible health and environmental benefits.
Can Cat Poop Be Used as Fertilizer?
Cat poop contains moderate levels of nitrogen, phosphorous, potassium and micronutrients that plants need Here’s a quick rundown
-
Nitrogen: Promotes green, leafy growth. Cat poop is relatively high in nitrogen.
-
Phosphorus Important for roots, flowers and fruit Cat feces contain moderate phosphorus
-
Potassium: Supports plant immunity and responses to environment. Cat poop is lower in potassium.
-
Micronutrients Cat waste contains small amounts of calcium, magnesium and more.
These nutrients slowly get into the soil for plant roots to use as the poop breaks down. Adding other organic materials to cat poop can help it absorb more nutrients and good microbes.
That being said, cat poop fertilizer might help your garden grow better. I also think it’s not a good idea to use cat waste as fertilizer.
Dangers of Using Cat Feces as Fertilizer
Cat poop can make the soil more fertile, but it can also be harmful to your health if you put it down right away:
-
Parasites and pathogens: Cat feces may contain toxoplasma gondii, campylobacter, E. coli, salmonella and other pathogens that can infect humans.
-
Environmental damage: Too much cat poop can leach nutrients into groundwater, causing algae blooms and reduced water quality.
-
Pet health risks: Parasites in cat poop could spread to your own cat if they ingest contaminated soil.
-
Odors: Fresh or improperly composted cat poop has an unpleasant ammonia smell that can linger.
-
Weed seeds: Undigested seeds in cat feces can germinate and take over garden beds.
For these reasons, it’s best to avoid using fresh cat waste as fertilizer, especially near fruits and vegetables meant for human consumption.
Safely Using Composted Cat Poop as Fertilizer
If you want to use cat poop as fertilizer, first composting the waste is essential to reducing risks. Here are some tips:
-
Choose an outdoor area away from edibles to fertilize, like flower beds or trees. Never near fruits and vegetables.
-
Compost thoroughly using high heat to destroy pathogens. Maintain temperatures of at least 140°F for several weeks.
-
Turn the compost frequently and add water as needed to encourage thorough, even heating.
-
Only apply small amounts of finished composted poop to avoid nutrient overloads in soil.
-
Wear gloves when handling waste or composted cat poop, and wash hands after.
-
Prevent pets from accessing soil fertilized with composted cat waste.
-
Wait 1 year before planting edibles in soil amended with cat poop compost.
Proper hot composting makes cat poop much safer to apply in ornamental gardens. But for food crops, it’s better to avoid using cat waste entirely.
Choosing a Cat Litter for Composting
To compost cat waste, the litter also needs to be biodegradable. Avoid standard clay litters, crystalline silica litter, and products with chemicals, fragrances or antimicrobials. Good compostable options include:
-
Paper litter made from recycled paper, cardboard or newsprint
-
Pine pellet litter made from compressed sawdust without additives
-
Wheat litter made from straw
-
Compressed wood litters
-
Corn, wheat or grass seed litter
Stick to unscented, chemical-free varieties of these litters. They’ll break down in compost, unlike clay that remains intact indefinitely.
Hot Composting Cat Waste
Hot composting is required to destroy pathogens like toxoplasma and E. coli in cat feces safely:
-
Build a large compost pile, at least 3 x 3 feet. The mass helps retain heat.
-
Mix in coarse materials like wood chips to improve airflow. Turn the compost frequently.
-
Monitor temperatures regularly. Heat compost to 140°F or above for an extended period.
-
Allow finished compost to cure for 6+ months after heating before using.
-
Do not use cat poop compost on edible gardens. Only fertilize ornamental plants.
The high heat eliminates risks like bacteria and parasites in cat waste. With the proper technique, you can produce a nutritious, pathogen-free compost.
The Bottom Line: Is Cat Poop Good Fertilizer for Flowers?
Cat poop certainly contains nutrients that could potentially benefit ornamental flowers. However, fresh cat feces poses major health risks if used as fertilizer for edibles or areas where children play.
Only use cat waste to fertilize non-edibles after proper hot composting. For food gardens, it’s safest to avoid cat poop altogether even when composted. With the right precautions, composted cat waste can be applied safely to boost non-edible flowers, trees and landscaping. But when in doubt, steer clear of fresh cat feces as fertilizer.
Deterring Pet Poop Composting in Garden Areas
It is clear that putting cat poop in compost is not a good idea. But what about cats that use your garden as a litter box? There are a few things you can do to keep cats out of your garden. Here are a few ideas:
- Spread chicken wire over the vegetable garden. Cats don’t like to walk on it and can’t dig through it, so they’ll be more interested in other possible “toilets.”
- Place cardboard covered with Tanglefoot where people enter the garden. Tanglefoot is a sticky substance that is used to keep wild birds away and catch bugs. Cats will only step on it once.
- Sprinklers that turn on when a cat walks through the garden are a good idea.
Ultimately, it is a cat owners responsibility to make sure that his pet (and its pet poop composting) doesnt become a nuisance. The best way to do this is to keep the cat indoors. You might point out to the cat owner that according to the ASPCA, cats that stay indoors contract fewer diseases and live three times longer than those that are allowed to roam.
Can Cat Feces Go in Compost?
Toxoplasmosis is a parasite that causes disease in humans and other animals, but cats are the only animal known to excrete toxoplasmosis eggs in their feces. Most people who contract toxoplasmosis have headaches, muscle aches, and other flu symptoms.
Toxoplasmosis can make people with immune-deficiency diseases, like AIDS, and people who are getting treatment that weakens the immune system very sick. Pregnant women are at significant risk because exposure to the disease can result in birth defects.
Reencle is the first electric composter to use an advanced microbial system to break down food waste that contributes to creating compost in just three weeks.
In addition to toxoplasmosis, cat feces often contain intestinal worms. Composting cat litter is not enough to kill the diseases associated with cat feces. In order to kill toxoplasmosis, a compost pile would have to reach a temperature of 165 degrees F (73 C), and most piles never get that hot.
Using contaminated compost carries the risk of contaminating your garden soil. In addition, some cat litters, particularly scented brands, contain chemicals that dont break down when you compost cat waste. Pet poop composting simply isnt worth the risk.
