Which oral flea and parasite medication is most effective for cats?

Hi and thanks for posting on Petco Pet Education Center, formerly Petcoach! For cats, I would recommend Revolution which a topical solution applied once monthly. It helps prevents fleas and intestinal parasites in cats. It is easy to use and very effective in cats. This is a prescription medication your can obtain through Jax's veterinarian. I hope this helps!

Yes, there are topicals you can use: Profender and Revolution are two that come to mind straight away. ( https://www.allivet.com/p-3497-profender-for-cats.aspx ) ( https://www.allivet.com/p-1902-revolution-for-cats.aspx )

Hi I would suggest you buy a box of 6 pipettes of Revolution. Make sure you apply one pipette on each cat to the skin to the back of their neck, so it’s important you part hair when applying it. You need to repeat it every month. I would also suggest you spray the environment to kill all eggs and larvae present. I am sure they will be able to advise you on which spray is best according to the size of your house and people living in it. https://www.petsmart.com/cat/pharmacy/rx-medication/revolution-for-cats-5.1-15-lbs-5273301.html

Flea and tick products: Spot-ons: Advantage, Advantix Advantage Multi (Advocate in the UK) Frontline (ticks as well) Bravecto spot on (ticks as well) - for cats, in tablet form for dogs Revolution (stronghold in the UK) Tablets: comfortis (will only kill fleas once) Collar: Seresto (ticks as well) Heart worm : Here is a comparison chart: https://www.drsfostersmith.com/pic/article.cfm?articleid=580 Usually there are no long term side effects.

If it is available, my best topical flea treatment for cats is Cheristin. It is very effective and kills fleas before they bite, which is helpful for cats with flea allergies since it is the bite they react to. Comfortis is a tablet that is also very effective, but it can cause vomiting.

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.

You received a highly effective preventive medication which also covers mites besides the ones you mentioned. Realize that your kitties probably are stressed out with the two moves, one away from the person they loved (yes hoarder kitties are loved too, and love their owner) to the shelter and then from the shelter to you. Give them lots of TLC and they will get used to their new home soon.
