Why does my cat's back twitch? Is it fleas, soreness, or worms?

Updated On September 23rd, 2025

Pet's info: Cat | Domestic Shorthair | Female | unspayed | 6 months and 20 days old | 6 lbs

Nala often twitches her back. She is an outdoor cat and we have a puppy that has caught her a few times and he must bight her because she is always wet when we find her but she never has any wounds. So I was wondering if she could be sore and this is why she twitches her back? Or might she have worms? Or why does she twitch her back?

Some cats can twitch their backs if their fur is overly sensitive to sensation. Most cats twitch their backs due to fleas so I recommend to treat her for fleas and use a good product such as Cheristan or Revolution. If the twitching stops, then you know it was fleas. Worms don't generally cause back twitching but they can cause GI upset if the numbers are high enough. Also, if she is not spayed yet, you need to get that done ASAP as cats will start cycling as early as 6 months old. I hope this is helpful and please post any additional questions.
