Tick control is difficult in cats as many of the products cause toxicity. Frontline Spray is the only product registered and tested for preventing ticks in cats and should be applied every 3 weeks. It is important to NEVER apply any tick product that is not specifically for cats as these may cause serious fatal reactions.
There are many products currently available on the market. Products such as Frontline Plus and Advantage cover fleas only when applied monthly. Other products such as Revolution and Advocate cover fleas as well as some species of mites and intestinal worms. Our staff are happy to work out the best product for your situation.
We strongly recommend desexing all animals that are not required for breeding. The main benefits of desexing are preventing unwanted litters, reducing undesirable behaviours such as urine spraying and roaming in males and reducing the risk of health problems later in life. These health problems include mammary tumours, ovarian and uterine tumours and uterine infections. The health benefits of desexing are maximised if undertaken before females first oestrus
We recommend desexing at 5-6 months age.
Cats are susceptible to roundworm, hookworm and tapeworm infections. They can become infected through contact with other cats, the environment generally or, most commonly in kittens, from their mother at birth. We recommend using a good quality allwormer product such as Drontal.
Kittens should be treated:
- Every 2 weeks until 3 mtgs age
- Then monthly until 6 months age
- Then every 3 months for life
Intestinal worms can also infect humans especially children so we strongly recommend ongoing intestinal worm control.
Vaccination is an important way of preventing disease in your kitten. We recommend that all cats are vaccinated against feline rhinotracheitis virus, feline calicivirus and feline panleukopaenia.
Kittens require an initial course of 3 injections:
- Initial kitten F3 (Due at 8 weeks)
- Second kitten F3 (Due at 12 weeks)
- Third kitten F3 (Due at 16 weeks)
After the initial course, we recommend that your cat comes in for an annual booster vaccination to ensure ongoing protection.
Kittens can be weaned from 3 to 6 weeks of age by gradually introducing solid food. We recommend that you use a good quality ‘complete and balanced’ diet such as Hills Science Diet. A ‘complete’ food is one that gives your kitten all the nutrition it needs so that you do not need to feed any other type of food. A ‘balanced’ diet means that all of the ingredients are in the proper ratios for your kittens health. The benefits of a good quality diet are faeces that are normal consistency and reduced amount compared to the cheaper brands.
Kittens should never be fed a meat only diet as this can cause serious nutritional disease. We recommend that you feed your kitten twice daily until 6 months age.
There are a number of different species of parasitic worms that infect horses. These include: ascarids (roundworms); large and small strongyles; tapeworms; pinworms; thread worms; stomach bots and lungworms.
Worms irritate the gut lining and lead poor digestion and absorption of feed. Most worms live in the intestinal tract and release eggs that are passed out into the paddock in manure. Eggs will then hatch and larvae develop in the manure and pasture.
Horses grazing grass that has been contaminated with infected manure will ingest the larvae, which then develop into mature adult worms and perpetuate the infection.
How can I tell if my horse has worms?
Horses that have a high worm burden may develop some or all of the following signs:
- Poor coat condition
- Poor weight gain or weight loss
Tests can be run on faecal samples to assess the current worm burden of your horse and identify any resistance to worming products that may be occurring. Regular worming of all horses on your property with an appropriate type and amount of worming product in conjunction with good pasture management, will effectively control worm burdens in your horses.

Basic Steps to good worm control
Below are some points to consider and suggested protocols for worming and pasture management.
- Worm ALL horses on your property every 6-8 weeks (or as directed by the specific product label). This is especially important in Foals, Mares and yearlings, as these animals are most susceptible to infection. Foals should be first wormed at 6-8weeks of age.
- DO NOT UNDERDOSE If possible, get an accurate weight on your horses by weighing them on scales or using a weight tape. If you are unable to weigh your horses, estimated weights should be rounded up to the nearest 50 kgs. All worming products have a wide safety margin, so it is safe to dose them a little higher. The use of sub-optimal doses of worming product will only promote the development of worms that are resistant to the worming products available. There are only a finite number of different worming product types. Once resistance is established, we will have no means of treating worm burdens.
- Regularly alternate the type of worming product used This reduces the risk of resistance to particular products developing. When selecting products to alternate with, try and use ones that contain different drugs. E.g. If you used Ammo Allwormer paste for horses, which contains Abamectin & Morantel Tartrate, 8 weeks later try Equest Plus Tape Long Acting Horse Wormer and Boticide Gel, which contains Praziquantel & Moxidectin. Followed by Equimax Oral Paste for Horses, which contains Abamectin & Praziquantel.
- Use feed bins This will prevent contamination of feed with infective larvae from the pasture.
- Pick up manure from paddocks 1-2 times per week This will reduce the number of infective larvae available to contaminate pasture.
- Spell Paddocks Where possible, rotate the paddocks grazed, allowing them to spell for at least one month – Spelling paddocks will reduce the number of infective larvae in the pasture. This helps break the cycle of re-infection
- Harrow paddocks after removal of horses Infective larvae dry up and die when exposed to heat and sunlight. Harrowing paddocks breaks up the manure and exposes more of the infective larvae to the heat and sun. This helps to further reduce the number of infective larvae in the pasture and helps break the cycle of re-infection.
- Rotation grazing with sheep or cattle This is another way of reducing the number of infective larvae in the pasture. Horses and sheep/cattle do not share the same types of parasitic worm species. By grazing cattle or sheep in paddocks, these animals ingest the infective larvae, but these larvae die and are therefore unable to reproduce. These animals therefore act to “clean up” the infective larvae from your pasture.
- Conduct routine faecal egg counts Faecal egg counts can be performed on faecal samples collected from you horses. Egg counts allow us to assess the current worm burden and give us an indication as to whether the worming products and pasture management used are effectively controlling the worm burden in your horses. Regularly performing faecal egg counts (every 6 months) can allow you to strategically worm your horses, so may allow you to worm them less frequently.
By introducing as many of the above mentioned steps as possible, you will achieve good parasitic control, whilst minimising the development of resistance to worming products.

What is Pestivirus?
Pestivirus is an extremely common virus in cattle herds, and it can cause a range of disease syndromes including reproductive failure, birth of abnormal calves, respiratory and diarrhoeal disease. Cows first exposed to the virus and infected during early pregnancy may abort, have deformed calves, or give birth to calves that appear normal but act as infectious carriers – these persistently infected (PI) animals perpetuate the disease within the herd.
What is a PI?
A persistently infected animal, or “PI” is one that was exposed to the virus while in the uterus, at a stage when the developing immune system mistakenly assumes the virus is a normal part of the animal (between about 1 and 4 months of pregnancy), this means the calf doesn’t develop a normal immune response and the virus continues to live on in the PI undetected, reproducing and shedding in huge amounts for the entire life of the animal. These animals later develop the clinical signs of Mucosal disease which causes chronic, antibiotic non-responsive diarrhea and ultimately death.
‘Classic’ PI calves are poor-doers and:
- Are responsible for most of the production-limiting outcomes of pestivirus
- A reservoir for year to year re-infection
- Often carry the infection between properties
Transiently infected animals will also shed virus, but for only a limited period of time, about 2 weeks.
Serology: Blood testing
Serology tests for antibodies produced by the animal as a result of Pestivirus infection. It can take up to 2 weeks from initial infection for antibodies to be produced, and these will remain for years after the virus has been eliminated.
A seropositive result means the cow has been infected at some time, but does not reveal whether it is currently infected with or shedding virus.
A seronegative result means the cow has never been infected with the virus.
NOTE: A PI animal will also be seronegative – because the immune system thinks the virus is a normal part of the animal’s body, antibodies are never produced.
Virology: Ear-notch testing
Virology detects the presence of the virus itself. The small vessels in the ear notch are analysed for the presence of virus particles. Samples are sent to a pestivirus-specific lab in Western Australia.
The lab will reports results as:
- Strong positives – extremely likely to be exposed to virus CULL or can retest in 2 weeks to be sure they are not transiently infected.
- Weak Positives – may be low shedding PIs or transiently infected retest in 2+ weeks to determine persistent from transiently infected.
- Negatives – not currently infected with the virus, but may have been in the past (in that case will be blood test positive)
Management is centered on location and removal of PI animals, combined with a vaccination programme for the rest of the herd, and there are various approaches which can be taken to achieve this aim. If pestivirus is a problem in your herd, or you would like further information on Pestivirus–please feel free to contact us at the clinic.
