Cat has daily diarrhea. Best flea/worm treatment: paste or tablet?

Updated On September 23rd, 2025

Pet's info: Cat | Siamese | Male | neutered | 1 year and 10 months old

Hi. I was just wondering what is the best brand to get for worming and flea treatment? and what is better; worming paste or tablets? Also, for some reason, one of my cats has diahorrea everyday and has had it for a while. What could be the issue? I thought it may be either worms or the food brand. I feed both my cats dine wet food and whiskas dry food

There are many different products for flea and worm treatment, but many have the same ingredients and work just as well as the others; so there's really no superior product amongst them. However, some stores will sell homeopathic products, or products labeled as natural, that are either not effective or far less effective than the medicated products. For this reason, I recommend only getting a product that is recommended by a veterinarian. For more information about treating fleas, please read the short article at the link below: https://www.petcoach.co/article/5-tips-to-get-rid-of-fleas/ When it comes to deworming, it actually depends on the type of worms that you are treating. In order to know this, Toby will have to be tested for worms at a veterinary clinic. Considering one of your cats has long-standing diarrhea, I recommend a visit to your veterinarian sometime soon. Long-term diarrhea is more concerning of an infection, or primary condition of the intestines like IBD. Worms are not a common cause of long-term diarrhea.
