The following plants and items could help to deter cats:
Citrus fragrance (scatter orange or lemon peels or spray with citrus)
Oil of lavender
Vinegar sprayed on areas where they roam
Pine cones and heavy bark mulch (cats don't like the feeling on their feet)
Dried nut of bean shells, broken egg shells, holly leaves, or rock mulch
You could also consider planting the following natural deterrents:
Curry plant - Helichrysum augustfolium, Geranium - Pelargonium
Rosemary - Rosmarinus officinalis
Scaredy cat plant - Plectranthus caninus , Lemon thyme - Thymus citriodorus
Lavender - Lavandula augustifolia, Pennyroyal - Mentha pulegrium
You can purchase commercial cat repellent sprays and gels from plant nurseries, vets and pet stores. These methods will only work if the cat does not like the smell of the product. Do not use a disinfectant that contains ammonia, as this may attracts cats to the area.
If you want to breed cats, you need to apply for a permit from the City of Belmont, in accordance with the Cat Act 2011.
Please speak to the City's Rangers on 9477 7224 to discuss requirements.
