CDL is not a suitable deworming treatment for cats. A disinfectant effect outside the body does not show that a chlorine dioxide solution safely and selectively treats intestinal parasites in an animal. Do not put it in the mouth, food or drinking water.
The veterinary approach
| Step | Why it matters |
|---|---|
| Discuss risk | Consider age, outdoor access, prey, fleas and previous treatment |
| Plan testing | Discuss appropriate faecal testing and its limitations |
| Choose treatment | Consider parasite species, body weight and authorisation for cats |
| Limit reinfection | Remove faeces and treat fleas when necessary |
A negative faecal test does not reliably rule out worms
A single sample may happen to contain no eggs. Faecal testing is particularly unreliable for tapeworms. The veterinary practice decides whether monitoring, risk-based deworming or both make sense for the individual animal. A pooled sample may help when collected according to the laboratory’s instructions.
Indoor cats can also become infected. Visible segments, diarrhoea or vomiting alone do not allow reliable selection of the active ingredient. Not every dewormer works against every worm species.
Do not copy a number of drops from the internet
A preparation for dogs or humans is not automatically suitable for cats. Weight, age, health and the veterinary medicine’s instructions must be consistent. Tell the practice about existing medication and previous reactions; do not use homemade chemical mixtures or substitute CDL regimens.
After accidental ingestion
If CDL ingestion is suspected, contact the veterinary practice or emergency veterinary service and have the label, concentration, time and estimated amount available. Do not induce vomiting yourself or give other substances to neutralise it. Seek immediate veterinary help for drooling, repeated vomiting, severe weakness or breathing problems.
Frequently asked questions
Are all cats worm-free after a negative test?
No. Test results and risk must be assessed together.
How often is deworming needed?
Intervals depend on the cat’s individual risk and the veterinary plan.
