my cat was treated 5 days ago with comfortis for fleas. she

Resolved Question:

my cat was treated 5 days ago with comfortis for fleas. she is an indoor cat only, with no other pets. she went to the vet about 3 weeks ago, shortly after that she started cleaning very aggressively and seemed agitated. we then noticed the black flea dirt and white specks. we believe that her trip to the vet she picked up fleas. how fast should the pill take effect, how long should we still see the black specks and her skin has a lot of white flakes. What should we do?

Dr. Whitehead :

Hello there. My name isXXXXX and I am sorry to hear about Lizzie and her fleas. Comfortis will kill all fleas on her within 4 hours and will last up to 30 days. So depending on where she caught the fleas then you may be still seeing them. Fleas do not actively jump off animals onto another. They will drops their eggs which hatch and develop in rugs/carpet/yards/blankets etc. Then those are the fleas that will jump onto animals. the life cycle can take up to 90 days to break so once you see fleas on an animal they should be on flea protection for at least 3 months. They will not lay new eggs during that time since they are dying off. Also you will want to vacuum any carpet she is on or near, wash beds or blankets she lays on or near weekly. This will remove any eggs or babies that may be left behind. You may see the black spots up to 90 days depending on where she picked them up and their population. If she picked them up at the vet and they did not have time to lay any eggs in the house then you should not really see the black spots for longer than a week or two. They will go away faster if she is combed and bathed. The white flakes are from dry skin and can be helped by giving her omega 3 fatty acids (fish oil) daily on her food. This is really common this time of year and not likely related to the fleas. But definitely stick the the comfortis and this should take care of the fleas and start her on a fish oil supplement. you can get this from your vet or any pet store. I hope this helps and I hope this makes sense. Please let me know if you have any additional questions or concerns. I would be happy to help. Please do not forget to rate my response so I receive credit for my time. Thank you!

  • My oldest male cat had a seizure this evening. This site was the first place I could think of to go after the seizure had passed. Dr. Lucy was fantastic and she was spot on! Debbie USA
  • I must tell you I found this site by accident and was amazed when I asked a question of the Veteranians online. I wish I could have found it sooner it could have made such a difference in the outcome of my pet's surgery. However, I am passing along the information to my sister-in-law (a cat-rescue person who is also a nurse), and perhaps it will help someone else who may experience the same problem. The doctor who answered my question was amazing, and while it didn't come it time to change the outcome of my situation, it is reassuring to know the caliber of Vets/Doctors that you have at JustAnswer. Thank you for being there. Alice H. Jacksonville, Fl.
  • Wonderful service, prompt, efficient, and accurate. Couldn't have asked for more. I cannot thank you enough for your help. Mary C. Freshfield, Liverpool, UK
