Can I give my cats their old toys back after worm treatment?

All kittens have worms. Get some kitten wormer today and worm them. Tell your children to wash their hands after handling the kittens and they should be fine. It only takes a few hours to get rid of the worms. However you will need to worm them again on about two weeks to kill the worms that have hatched from eggs present. If your children are very young and not able to comprehend that they will have to wash their hands, then it may be a good idea to separate them from the kittens for the next 2-3 weeks until the kittens have had their two doses of wormer.

Washing his bed is a good idea. You do not need to throw away his toys. You can wash those too. Depending on what wormer you are using you may have to retreat your puppy in two weeks.

Yes, worms can be passed from mom to babies. Most kittens will have 1-2 dewormings before they are fully weaned from mom once they are a bit older. It is best to talk to your vet to see if it's safe to deworm the mother and when the kittens can get started on their own deworming protocol.

1. The only concern for human beings is the transmission of certain tapeworms. These are transmitted by fleas and incidental ingestion of the flea can cause infection. I would not be worried about roundworm, but fleas need to be treated as well as gastrointestinal worms. Normal hygiene precautions must be followed though (wash your hands). 2. You can pet him without problems. 3. Eggs can be present of course and usually bleach is enough to disinfect the area appropriately.

Yes, adult worms will not survive in the environment but the eggs can survive in fecal matter so be sure to clean up after any accidents. Take a sample of the worms for identification to be sure she gets the most appropriate treatment as soon as possible

Unfortunately there is no way to stop cats from shedding the tapeworm segments. You don't have to keep her quarantined if you don't want to . I understand the segments are gross and you have a toddler but the segments are not harmful. The only way your toddler would get tapeworms would be from ingesting an infected flea. I would be more worried about getting the fleas under control. So, if Yuki had fleas, they are definitely in your house so you should treat the house for fleas as well.

It's definitely a good idea to clean and sanitize everything after your cat has had worms just to prevent spreading it back to your cat (or yourself from contact with any affected material as roundworms are transmissible to people and other pets). I would make sure at the very least to completely change the litter, wipe down the litter box with a sanitizing wipe, and wash any bedding your cat regularly sleeps on including your own, their beds, the couch, etc. This can help get rid of any roundworm eggs that may still be in the environment as it can be spread through fecal matter.
