Indoor-only cat can get fleas from human. If you went to grassy area, fleas can jump on your shoes or pants then being carried into the house. Changing shoes before entering the house might help. Bathing is a safer way than the neck drop. But the cat need to be trained to get used to it. Remember to be gentle since they are naturally afraid of water. -Use the sink instead of bathtub, use shallow water, let them feel safe, and lot of treats love after each time! !Important note! You need to watch for tapeworm now. Tapeworm can infect flea. If the flea was swallowed by a cat, then the cat will get tapeworm from that. You can google 'cat tapeworm' to find out more. Good Luck!
我有经验，在家也会有，可能人带进来，或者猫在窗口看风景，缝隙里钻进来。反正我家全部在家，也有过跳蚤，夏天必须用药。
已经有了跳蚤的话处方的revolution挺好的，杀干净之后最多三个月半年一次，我都尽量不点。天然的硅藻土也行，但是比较难操作。
我们不喂raw，我就没内驱。每年验血验便一次。我家猫一直在家都没事，就那一次中招了，而且刚巧她对flea过敏，挠的惊天动地的。当时去vet那边滴了药，打了过敏针。现在每年夏天给带驱虫项圈，以防万一。
不用那么担心，驱虫药和疫苗在我看来都是过犹不及。即便是生食，用可靠渠道的食材也不用驱虫
似乎也不对，我家咩咩原本是野猫，现在半家养，晚上抓回来睡白天一定要出门那种。以前游走的范围比较广，偶尔还会和别的野猫干架，就算定期点外驱但身上还是时不时有跳蚤。最近这半年他的活动范围变小，基本就只在自家和隔壁院子，每晚回家都会给他擦毛检查，三个月没点外驱也是干干净净。 他的饮食长期就是干粮偶尔罐头。感觉还是环境因素居多，还有就是活动范围以及接触源。 家里另外的小猫也是，从来没用过外驱，但也从来没跳蚤，她可是从小就和咩咩接触的。
