cat not eating but otherwise OK

[sphil]

She's a rescue cat and we've had her since Sept. She is approx 18 months old. She used to eat all her wet food in one go but for a few weeks now she's just been nibbling and then leaving it. She's never eaten many biscuits and still isn't! I've tried different brands, different flavours - she rejects them all. Put a post on here last week to ask whether it was anything to do with her teeth - they are protruding - but the answer was that it was normal ( the teeth I mean). She is behaving normally otherwise though seems to be indoors much more often ( she is allowed out all day but we keep her in at night).
Just fussy? Or shall I take her to the vet?

Is she losing weight?

How much is she eating in a day and how often are you feeding her?

If she's not losing weight and you work out that actually she's eating a fair amount through the day tbh I'd just feed her less at once. If she's thinner or she's really not eating much altogether I'd take her in.

Mine eat 2 pouches a day and the odd mouthful of biscuits - but they are fairly tiny cats anyway.

She only gets one dry meal and one wet meal a day - she eats maybe a quarter of a bowl of biscuits and, at the time of my original post, hardly any wet food at all. However this evening I went into the garage where she is fed (it is connected to the house by a door and cat flap and has outside access as well) and she ate about half a bowl full. I am wondering whether another cat has been in and scared her, as she seemed happier to eat when I was standing there and kept looking up and round while she was eating. I may try moving her food into the kitchen for a while and see if it makes a difference. She isn't losing weight but she only weighs 2.5kg anyway - has put on 0.5kg since we got her (but some of that is just growth).
