This is an issue that's occurred in this past week and I still can't get my head around this. My cat has been friendly/passive for the 2 1/2 years I've had her but a few days ago she suddenly started hissing, growling, and clawing at my legs. Just for the record, I know the clear difference between playing and hostile behavior and I'm pretty certain that this is the latter.
What throws me off even more is that I haven't done anything to deserve this! I treat her very well and I'm the one who feeds her at least half the time. On top of that, this has happened 3 times in the past week but every time it happens, my cat seems to forget about it an hour later and just go back to the cat she's always been. As far as I know there has been no clear change in anything and my cat shouldn't suddenly be sick (I think if she was sick then the behavior would be more consistent?).
Just to reiterate, when this happens she is hissing loudly and assumes a defensive, agitated stance when we make eye contact but will follow me around (presumably waiting for me to turn around or some other opening to attack?). This didn't happen every day since it started and only last a short period of time. I don't get it!
If anyone understand why my cat would have such unexpected behavioral changes please let me know
On a side note: is there some kind of outdoors scent that cats would react very negatively to? I've recently been biking around town but I don't think I've picked up any specific animal scents along the way. Even if I did, she doesn't react this way immediately anyways. I'm bringing this up because it seems to be coincidental that she starts behaving this way (and again, inconsistently) around the time when I started to bike. Still just a theory on my part though.
