Why does my tabby cat hiss every time I walk past, even though he’s been fixed for years?

Lately, every time I walk past my tabby cat, he hisses at me, which is unexpected since he's been fixed for years and never used to behave this way. I've tried giving him space and speaking to him calmly, but the hissing continues, and I'm not sure what might be causing this change in behavior. Could it be a sign that he's feeling unwell or stressed, and should I look into getting him checked by a vet?

Answer

It's concerning when a cat's behavior changes suddenly, especially when it involves hissing at a familiar family member. Since this behavior is new, it may indicate that your tabby cat is experiencing stress, discomfort, or a health issue.

  • Observe for other behavioral or physical changes
  • Consider recent changes in the home environment
  • Consult a vet if unsure or symptoms escalate

When a cat begins hissing unexpectedly, it can be a sign of stress, fear, or discomfort. Health issues such as pain, illness, or even mild irritation might be the underlying cause. Since your cat has been neutered for years and this is new behavior, it is important to consider if there have been any changes in his environment that might be contributing to his stress, like new pets or visitors in the home. If nothing has changed in the environment, or if your cat shows other symptoms such as lethargy or changes in appetite, it would be wise to book a consultation with a vet.
