Judging from the performance of a cat with worms in its belly, weakness is indeed a common performance. But if you judge what kind of parasite it is, the score depends on whether it is roundworm, tapeworm, hookworm or heartworm.

Generally speaking, cats infected with parasites will have weak performances such as dull coat color, weight loss, diarrhea and vomiting. At the same time, parasites will be excreted, and crawling or dried worms may be hidden in the anus and cat litter of cats. Insect repellent is a preventive measure, which belongs to the necessity of keeping cats. It is necessary to kill internal and external parasites by using insect repellent such as Brian regularly, so don't ignore it because of luck.
