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.
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.
Vinegar as a cat repellent
Spraying Outdoors – Straight or diluted vinegar can be sprayed around the edges of a garden, and on plants, fences, posts and garden décor to keep cats away. Concentrate the spray on areas that the cats frequent or that you particularly want to protect.
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. Motion-activated sprinklers: These have motion sensors that trigger a short blast of water.
Mint, wintergreen, and menthol. More smells cats hate include mint and strong mint-related odors, such as wintergreen and menthol. This may be for good reason, as ingesting mint and its relatives can cause vomiting and diarrhea in cats.
Citronella oil is a homemade cat repellent that many people have had success with. Citronella is best known as a mosquito repellent, but cats find the Citronella odor to be distasteful. Simply mix one part Citronella oil to four parts water and spray liberally in the troubled areas.
To keep cats away from gardens, flower beds, or specific areas of property, scatter fragrant items that don't appeal to a cat's sense of smell, like fresh orange or lemon peels, organic citrus-scented sprays, coffee grounds, vinegar, pipe tobacco, or oil of lavender, lemongrass, citronella, or eucalyptus.
Try orange and lemon peels, cayenne pepper, coffee grounds, lavender oil, lemon grass oil, citronella oil, peppermint oil, eucalyptus oil, and mustard oil. You can either sprinkle drops directly onto your flower beds or soak a cotton wool around it and place at entry points. One sniff and they'll be gone.
Keeping Fleas and Ticks Away
To make your own flea and tick repellent, mix one part vinegar with one part water and spray it on your pet's fur. You can also add a few drops of vinegar to your pet's drinking water to help repel fleas and ticks from the inside out.
You can try orange and lemon peels (cats dislike citrus scents), the herb rue which can also be planted live, cayenne pepper, coffee grounds, pipe tobacco and various oils, including lavender, lemon grass, citronella, peppermint, eucalyptus and mustard.
Cleaning the area thoroughly with vinegar first and then applying an enzyme treatment will break down and evaporate the uric acid and your home will be free of cat odors. Vinegar and enzyme cleaners work on all surfaces: hardwood floors, carpets, mattresses.
Peppermint oil is highly toxic to cats.
Without the enzymes required to break down phenols, cats exposed to peppermint oil can experience: Liver damage. Breathing difficulties. Wobbliness and seizures.
Pest control products such as moths are frequently used in gardens to keep cats at bay. Cats find it irritating when they smell mothballs. However, not all cats will flee.
Cats, being fairly territorial, are unlikely to feel comfortable doing their business in a place that smells like another, much larger, feline already frequents it. Put down extra strength hot chilli powder. It annoys cats' paws and whiskers without causing them serious harm. They'll stay well away.
Push the Catwatch ultrasonic cat deterrent into the ground, and when the sensor detects movement it emits a high-pitched sound disliked by most cats (but inaudible to humans). The frequency emitted is unique to cats hearing range, so the Catwatch won't bother other garden wildlife, such as hedgehogs.

Cats dislike eucalyptus, lavender, lemongrass, and peppermint – just choose the ones you don't mind the scent of yourself.
Lavender (Lavandula)
Luckily, lavender plants come with a scent that's nice for us but unappealing for felines. These purple flowers are evergreen, so they act as a year round deterrent. Choose the tall varieties and plant them at the front of your borders as cats won't jump over if they can't see where they'll land.
Scented litter
A thin layer of baking soda placed on the bottom of the box will help absorb odors without repelling your cat.
They will be killed by coyotes, eagles, owls, raccoons, dogs and otters. Two cats were killed by an otter when the cats got to close to their nest. Cars and humans also kill cats. PAWS regularly sees cats which have gunshot wounds or vehicular injuries.
Loud noises
In the home, cats are often scared of noisy household appliances, especially if they didn't become accustomed to them as young kittens. Vacuum cleaners, lawnmowers, printers, washing machines and hairdryers are common culprits.
The mystery of why cats hate cucumbers is normally explained by the natural fear cats have towards snakes. To a feline's eyes a cucumber can look similar enough to the pesky reptile to elicit their fear response and make them jump a few feet in the air to avoid being bitten.
