Cats dislike eucalyptus, lavender, lemongrass, and peppermint – just choose the ones you don't mind the scent of yourself.
Cats are more sensitive to scents than humans, so essential oils with strong odors, such as citrus and lavender, can help repel them. You can substitute lime, peppermint, and/or eucalyptus for the lemon, wild orange, and lavender if you prefer.
Citrus or lemon scents (orange peels, lemon peels), garlic, ammonia, vinegar, coffee grinds, pipe tobacco, mustard, citronella, or eucalyptus all deter cats as well. The scents diminish over time, so re-applying is necessary.
What you need: An essential oil (citronella, citrus), spray bottle, water. You should avoid using peppermint and lavender essential oils as they can be harmful to the cats. Mix one part essential oil to three parts water in the spray bottle. Spray in areas that you want to keep cats out of.
Mix together lemon juice, rosemary and white vinegar - three things cats detest. Put the liquid in a spray bottle so it's easy to use around the garden. Simply spray near where the cats spend time - on planters, the patio, or even inside.
Eucalyptus oil is used as a deterrent for numerous animals, among them fleas, mosquitoes, mice and rats and — and you guessed it — cats. Use both of these natural repellents to your advantage.
As a general rule, cats are sensitive when it comes to smells, but there are a few scents they hate that might just surprise you. They can't stand citrus and as much as you might love the smell of fresh herbs, cats hate rosemary and thyme. Banana and mustard are a big no-no too, as well as lavender and eucalyptus.
Cats dislike the smell of certain scents, such as citrus, eucalyptus, lavender, peppermint, and rosemary. You can use these scents to deter cats from entering certain areas of your home or garden by using essential oils, planting these plants, or using citrus peels.
Many liquid potpourri products and essential oils, including oil of cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, tea tree (melaleuca), wintergreen, and ylang ylang, are poisonous to cats.

Likewise, geranium and eucalyptus plants give off an odor that cats dislike. Keep in mind that lavender, geranium, and eucalyptus are all somewhat toxic to cats; if ingested, they can cause excess salivation, nausea, vomiting, anorexia, depression, or dermatitis.
Many veterinarians and other pet care experts recommend not using tea tree oil for cats, even though it has been considered a safe and effective remedy for some feline complaints in the past. Tea tree oil is one of several essential oils, such as peppermint oil, considered toxic to these animals.
Toxicity to pets
Small ingestions of a few leaves or low concentration eucalyptus oil leads to mild gastrointestinal distress, but ingestion of highly concentrated eucalyptus oil has been associated with severe signs including seizure, tremor, and, rarely, acute renal injury.
While a lavender plant itself isn't toxic to your cat, formulations from the plant can be. Your cat can eat a lot of lavender and may suffer only an upset stomach, but on the other hand, lavender essential oil can be deadly for your pet because of its concentration.
Many cats do not like the smell of peppermint as it contains Salicylate which is poisonous to cats. Unfortunately, some cats are attracted to the peppermint plant because it contains Nepetalactone mimicking compounds, the active ingredient in Catnip.
Signs of lavender toxicity in cats include diarrhea, vomiting, and weakness. However, your cat may also experience respiratory symptoms when inhaling lavender essential oils, including coughing and wheezing.
Lavender seems to be the best researched essential oil for use with cats when diffused. Although scientific evidence supports its calming effect on cats when diffused, it can still be toxic if applied topically neat or undiluted to your cat's skin or fur, as can any essential oil if undiluted.
Lavender
Cats seem to hate the smell of lavender since the strong scent can be too much for them. Lavender plants can also be used as a natural repellent in your garden for cats.
Orange and lemon peels (cats dislike citrus smells), cayenne pepper, coffee grounds, pipe tobacco, lavender oil, lemon grass oil, citronella oil, peppermint oil, eucalyptus oil, & mustard oil.
Scent deterrents will either serve to repel (eg Citronella) or mark a territory (eg Silent Roar). Alternatively, try orange or lemon peel, since cats are not keen on the smell of citrus. A bucket or water pistol full of water, directed near but not at the cat, will help to chase an unwelcome cat out of the garden.
Squeeze 2 drops of lemon essential oil, 2 drops of wild orange essential oil, and 2 drops of lavender essential oil to the bottle. Cats are more sensitive to scents than humans, so essential oils with strong odors, such as citrus and lavender, can help repel them.
Cats are especially sensitive to many essential oils and even just a couple of licks can be harmful. Many essential oils, such as eucalyptus oil, tea tree oil, cinnamon, citrus, pennyroyal, peppermint, pine, sweet birch, wintergreen, and ylang ylang are toxic to pets.
