The paralysing kind. If you live in a tick area, you will usually know you do as these are dangerous pests. The paralysis tick takes 3 days from attaching to your cat and starting to feed before it starts injecting its poison into your cat’s blood stream. So you have 3 days to find it – check every day, every where. If your cat goes off her food and her voice changes – START CHECKING AGAIN for the tick https://www.youtube.com/watch?v=6c7LMlzYWgU If you fine one, remove it and take your cat to the vet anyway. If you wait till your cat goes wobbly, it will be a longer stay and a much worse illness. PREVENTION is better than cure – Bravecto spot on and Seresto collars are VERY effective and affordable. Revolution PLUS (not the standard one) is also highly effective. But your cat has to be treated BEFORE the tick has a chance to attach.
