Thanks for using Petco Pet Education Center, formerly Petcoach! They can be when used appropriately. However, it is very important to find out if there are worms present so that the one that is used is used against something in particular. If the right dose is used, in general dewormers tend to be safe. If you are concerned about worms in your kitty, it would be best to have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a great day!
