hi. i need some help. like title. she doesn't eating anything for a few days. any help? thank

A few days? Your cat is probably sick, please take the cat to a veterinarian as soon as possible.

Is she drinking? Does she seem happy, usual self otherwise? Maybe she's been 'eating out' if someone nearby also has a cat, or a neighbour is putting out food for her?

Please consult a vet ASAP, I know there is at least one psychologist here, but I've yet to meet a vet.

Best wishes, for your fur baby!
