Hi there! Yes, Advantix would be a very reasonable choice to use along with Sentinel Spectrum. You could also use Nexgard or Bravecto for tick coverage, if you prefer an oral medication instead of topical.

Thanks for using Boop by Petco! If you are talking about a praziquantel injection, I think the Sentinel is a much better option. The injection burns and it only treats one type of parasite. The Sentinel treats many. I recommend the Sentinel. Kisses to Penny!

Even though Sentinel spectrum is not licensed for cats, in this case there should be no problem with this medication and dosage as the ingredients (milbemycin oxime, lufenuron and praziquantel) each are licensed for cats. There is not enough of each in the 2-8lbs dog dosage to hurt your kitty. I suggest you hide the rest of the sentinel so Maurice does not find it. Praziquantel tends to sometimes make cats vomit, so this could happen within the next 30 minutes or so. This should not be a problem.

Sentinel has no tick coverage and does not kill fleas. It only sterilizes the eggs. I always go up a size to be safe as most dogs gain weight but rarely lose weight. It has a good safety margin so using the 25-50 pounds medicine would be best. You will continue to need the Simparica or nexgard with this

It should start killing worms within 24 hours. Penny will need another dose of it in two weeks to kill all the worms. This is due to the life cycle of worms. There will be eggs that will not have hatched yet at the time of the first deworming, so another needs to be given in two weeks to kill those when they do hatch. I hope this helps!
