In parts of Australia, ticks can cause serious illness in cats, including tick paralysis, which is a veterinary emergency. Tick risk varies by region and season and can change with weather patterns.
The University Veterinary Teaching Hospitals in Sydney and Camden provide expert guidance on tick prevention for cats, early recognition of tick‑related illness and urgent veterinary care when required.
Both the University Veterinary Hospitals in Sydney and Camden have experience managing tick‑related illness in cats and provide evidence‑based prevention advice. Our team is supported by specialist emergency and critical care services in Sydney 24/7 emergency hospital when urgent treatment is required.
Ticks are external parasites that attach to cats and feed on blood. Some species release toxins while feeding, which can cause illness ranging from skin irritation to life‑threatening paralysis.
Cats are affected by ticks slightly less commonly than dogs, but when illness occurs, it can progress rapidly and require urgent treatment.
Tick paralysis is caused by a toxin released in the saliva of certain ticks. This toxin affects the nervous system and can interfere with muscle function and breathing.
Tick paralysis occurs when a neurotoxin from a feeding tick disrupts nerve signal transmission, leading to weakness and, in severe cases, respiratory compromise.
Paralysis ticks are commonly found along the east coast of Australia, including the Sydney region. Cats may be exposed in bushland, suburban gardens, and outdoor or semi‑outdoor environments, with risk present year‑round.
Signs of tick paralysis in cats can be subtle at first and may be harder to recognise than in dogs.
Early signs may include lethargy, weakness, reduced appetite, vomiting or changes in voice. Some cats may become quieter or reluctant to move.
Advanced signs include severe weakness, unsteady walking, difficulty breathing, collapse or sudden deterioration. These signs require immediate veterinary attention.
If you find a tick on your cat, contact your veterinarian for advice as soon as possible. Monitoring for symptoms is essential, even after a tick has been removed.
Tick removal may be appropriate if done promptly and correctly, but incomplete or improper removal may increase toxin release. Veterinary advice is recommended, particularly if your cat appears unwell.
Cats showing weakness, breathing changes, vomiting or collapse should be seen by a veterinarian urgently, regardless of whether a tick has been found.
If you live in a tick‑risk area, prevention is essential.
Recommended strategies include:
Tick prevention for cats may include topical treatments specifically formulated for feline use. Your veterinarian will recommend a product appropriate for your cat’s age, weight and lifestyle.
Regular tick checks should focus on the head, ears, neck, under the collar, between toes and under the tail. Grooming can help detect ticks early.
Reducing access to dense vegetation, managing lawns and limiting wildlife exposure around the home can help reduce tick risk.
Tick activity often increases during warmer months such as spring and summer. However, ticks can be present year‑round in Sydney, so ongoing vigilance is important.
Tick paralysis requires prompt veterinary treatment to reduce toxin effects and support recovery.
Treatment may include tick removal, administration of tick antiserum, respiratory support and close monitoring. Hospitalisation is often required for moderate to severe cases.
Yes, cats can develop tick paralysis, although it is less common than in dogs. When it occurs, it can progress quickly and requires urgent veterinary care.
Early signs may include lethargy, weakness, vomiting or changes in voice or behaviour.
Using a cat‑safe tick prevention product and performing regular tick checks provides the best protection.
Indoor cats can still be exposed to ticks brought into the home, so prevention may still be recommended in tick‑risk areas.
Yes, ticks can be active year‑round in Sydney, even outside peak seasons.
