It does not take a coffee lover to identify the smell of freshly brewed coffee in the morning. Coffee has its own signature aroma and is as much appreciated for its smell as it is for its taste, especially by coffee aficionados.

What makes this smell so uniquely identifiable is its blend of chemical compounds that are volatile and add nuances to the aroma.

The chemical compounds in coffee that are responsible for its aroma are high in quantity and very volatile. This results in a very strong smell as compared to tea.

And cats, who have very sensitive noses, pick up on the aroma of coffee with much more intensity than a human nose would.

What Are The Advantages Of Using Coffee Grounds As Cat Repellent?

What Are The Advantages Of Using Coffee Grounds As Cat Repellent

There are 3 major benefits to using coffee grounds to make your DIY cat repellent.

1 – Coffee grounds are as good as manure for your garden soil.

The coffee grounds that you put into the soil of your garden’s periphery actually act as manure for the soil. It decomposes over time and nourishes the soil.

2 – Coffee grounds make for one of the least risky scent-based cat repellents.

Since coffee grounds mix into the soil and don’t have any distinguishing appearance, the stray cats will not try to eat the grounds.

This is a great risk aversion because usually, especially with other scent-based repellent substances like eucalyptus and rosemary, some curious cats may try to lick or chew the plants.

This accidental ingestion can cause severe health problems for cats; it may even prove fatal.

This risk of accidental ingestion is prevented by using coffee grounds because they mix in with the soil well. Even curious stray cats have a very rare chance of ingesting coffee grounds.

3 – Coffee grounds are one of the easiest accessible ingredients to make your DIY cat repellent.

This is by far one of the biggest advantages of using coffee grounds to make your cat repellent.

Almost every household has either coffee beans or instant coffee available at all times in the kitchen cabinet. You don’t need to buy anything extra to make this cat repellent.

What Are The Dangers Of Using Coffee Grounds As Cat Repellent?

The only single danger of using coffee grounds as cat repellent is that in the rare case that one odd cat accidentally ingests coffee, it can prove fatal.

Caffeine poisoning in cats leads to increased heart rate, increased blood pressure, nausea, and sometimes, even death.

However, this particular danger can be avoided by being mindful and thoroughly mixing coffee grounds with soil.

This is why it is advisable to dig up a thin layer of soil and mix coffee grounds with the soil instead of simply putting the coffee grounds on the periphery of the garden.

You should note that whenever you opt for any essential oil to keep the stray cats away, always put the oil in an aroma diffuser and only let the vapors spread the aroma.
