Can I apply Frontline to my injured cat after vet treatment and shots?

Hi, thanks for using Petco Pet Education Center, formerly Petcoach! Yes, but apply the topical medication to a healthy area of skin. Do not apply it to a scratch or open sore. Luey should probably be seen by a vet and given a steroid injection and an antibiotic if his skin is that bad. It will provide him with relief and help the wounds heal more quickly! I hope this helps and I wish Luey a speedy recovery!

Snoops' wounds look great! He looks completely healed, so no worries about flies and maggots. The shaved areas may get sunburn, so keep him indoors during peak sun hours. Just leave that scab alone if it isn't bothering him. I hope this helps!

Yes it ia sbsolutely ok to treat her for fleas. I would use a spot on such as Advantage or frotnline Plus or similar spot ons. and you can get some Pyrantel Pamoate from your veterinarian to worm her (it is a liquid, that does not taste terrible) or a Drontal for cats tablet.

Luckily that doesn't look too bad. I would gently clean Snoops's wound with warm water and antiseptic soap. Keep the wound clean and dry, and monitor it for signs of infection. If you see redness, swelling, warmth to the touch, or pus, then it is infected and he will need to see the vet for antibiotics to treat it.

Since both Sentry and Frontline use the same active ingredient (fipronil) it is unlikely that you will see better protection switching to the Frontline. You will need to choose a product with a different ingredient, like Advantage or Revolution or a Seresto collar. If you choose to use another topical, I would recommend bathing your kitty today to remove any remnants of the Sentry, and wait 3 days to apply the next topical. It is important to wait after bathing so that the natural body oils have time to coat the skin to ensure adequate absorption. You do not need to wait or bathe to use a Seresto collar.

That wound on his foot looks swollen which is concerning for a deeper infection or a wound to the bone structures in the leg. I recommend to get this examined since a physical exam is the first step in determining the extent of the injury. As for the fleas, top products for cats are topicals such as Revolution and Cheristan. There is also an oral product called Comfortis that both dogs and cats can take. You will need to switch all the pets over to a good flea product. Make sure to discuss these products with your veterinarian first. These products are generally safe for all pets but there are some conditions which are contraindicated for the oral products. Cleaning up and treating the house and yard will also help but it will not clear all the fleas. The main control is making sure the pets are on good products. This is what will ultimately stop the infestation. Also remember every female fleas lays about 50 eggs a day and it could take up to 6 months before the eggs hatch. Therefore, you will need to treat for at least 6 months. Best of luck and please feel free to post any additional questions.

The two treatments are not closely related but I would still recommend 7-10days before reapplying. You do not mention why you washed off the advantage but I would recommend combing with a flea comb to remove fleas in the meantime if still present. It may be worth considering using comfortis or capstar tablets if he does not tolerate spot on medications (it is often the carrier and not the active ingredient that pets are sensitive to)
