The same as with the rest of the animals, our cats are victims of external parasites. The most common one in cats are fleas. They also suffer (in a lower percentage) of ticks.
Even if our cat keeps itself clean, it can have fleas. Mainly if it is a fan of going out around the neighbourhood.
Fleas are quite difficult to spot. We can see if they have been near our cat if we move the hair from its stomach and we see tiny black spot which represent the faeces of these parasites. A bite of a flea can complicate up to the point of becoming a moist exem in those cats which are allergic.
When we detect an adult flea on our animal, we need to know it lays eggs in the middle. Then, it mounts the host. Due to this, we need to treat our cat with a product which guarantees its permanence to avoid future infections.
There are several types of products:
Pipettes: they are quite comfortable since they spread throughout their organism after being applied to one spot. They can be used in animals which are older than 2 months.
Spray: we need to apply them all over their body. However, we need to be careful not to apply it in their eyes, and any mucous areas. When they are too young, we can use some brands. I don't advise for you to apply it directly over the animal. It is better if you apply it on a gauze and then rub your cat with it. This will guarantee it won't get in its eyes or mucous areas.
Tablets: these are easy to use. However, fleas die after biting the animal. Due to this, any problems of allergies are not avoided.
Above all, before using any of these products, we need to reed the indications carefully or ask our veterinary. There are so many products in the market it would be impossible to explain each one of them here.
