When can I let my new kitten join my other cats after flea treatment?

You should wait 7-10 days before introducing the cats to each other. That way you can monitor them for any upper respiratory signs. I would be most worried about that. After the 7-10 days, if there are no URI signs you can introduce the cats to each other. Use proper technique - see link to an article below - to avoid behavioral problems. The best thing to do is treat all the cats with Revolution in 3-4 weeks just to be safe. It won't hurt them if they don't have roundworms and it will treat them if they do.

You can use Frontline spray on all cats, which should not be detrimental in case they groom each other. Unfortunately fleas hop on to drink and then hop off again and live in the environment. So you need to put flea powder in your vacuum cleaner and regularly vacuum your house that kill all fleas, eggs and larvae.

Yes, it is safe for your kitten to be around him. i do not recommend using any Hartz products, they are terrible and side effects are so common. here is the list of the best flea products on the market. Spot ons: Revoulution Advantage Advantage Multi ( Frontline (ticks as well) Bravecto spot on (ticks as well) Tablets: Comfortis Collar: Seresto ( (ticks as well) House spary: Indoorex

Dewormers generally work pretty quickly, I would recommend keeping them away for at least a week. There are several respiratory infections cats can carrier and infections can spread quickly between cats especially from a shelter. That 7 day period will give you time to schedule an appointment at the vet to make sure the kitten is healthy and make sure there is a feline leukemia and aids done to make sure she is negative.

Coccidia can be treated fairly easy. I would suggest you keep your cat separated from the kitten until the kitten's stool is free of coccidia. If you adopt the kitten while under treatment for coccidia, keep your cat and the kitten separate and give them their own litter box. If properly treated, your new kitten should recover fully and I do not foresee long term issues. Thank you for using Petco Pet Education Center, formerly Petcoach. Have fun with you feline friends!

All the cats in the house will need to be treated with the deworming treatment and flea treatment. If two of the cats have fleas, then the third likely has them as well and needs to be treated. Even if the third doesn't at the moment, there will be fleas in the home, and it could easily get them, so it does need protection. In addition, it is possible that your third cat also has tapeworms. I would get an additional flea treatment and deworming treatment, and give both to all of them. As for treating the house, I would wash all the bedding in hot soapy water. Vacuum the furniture and carpet surfaces. You can use a spray to kill fleas in the house, such as Indorex, or a flea bomb would work well to kill the fleas in the home. In terms of your twins, keep them out of any rooms where you use the spray (same for the cats) until the spray is fully dried. If you do decide to flea bomb the house, remove the cats and your twins for the entire day. At the end of the day, it should be safe to bring them back home. You can talk to an exterminator to get more help on this issue.

Make sure your dogs are up to date on Frontline as well so they cannot get ticks. The Frontline should act pretty quickly to kill all the ticks, and I would do a thorough check over Na's body to make sure the ticks are all gone. If he has no more ticks on him and your dogs are up to date on their flea and tick medication, it's fine to bring them together. I hope this helps!
