Hi, it's my first time using reddit:)
It's my first time owning a cat after so many dogs. I've had her since 2018. She's a female, I'm not sure about her age (different vets had told me different answers) but she's an old cat for sure.
I've noticed that today, after eating some grass and throwing it up, she's been throwing up frequently, it's mostly this watery kind of liquid.
She tried eating some of her food but didn't hold it down, now she's tired after feeling sick, she's trying to sleep...I'm taking her to the vet tomorrow as early as possible, I just want to know if someone has experienced this?
(I don't know if this is helpful but I asked my sister that has five cats and she told me that my cat might have an irritated mucosa. One of her cats had thrown up in the same way before...could it be?)
