My cat is 1 yr old male, neutered. Good appetite/weight/activity and sleep. 4 months ago I noticed blood in his stool and he was meowing in pain when pooping, the vet diagnosed him with worms and gave him the deworming tablet. 1 month later I noticed a spot of blood, the vet gave him a repeated dose of the dewroming. He's been fine till now he had soft yellow poop with blood in it. I already gave him the prophylaxis deworming tx 2 weeks ago, what can I do now? He eats wet and dry, and drinks wel

Hi and thanks for posting. I would be sure to recheck a fecal test with your veterinarian. Certain parasites and intestinal worms take several round of dewormer to completely get rid of. A follow up fecal test will be able to determine whether or not Larry has cleared the infection. I hope this helps!
