Help with two female cats

[CoQ10]

Hi all
Advice please!

My children each own a one year old cat (sisters).

One is timid and quiet, very good natured and sensitive; she's the smaller of the two and is happy with two meals a day with biscuits in between.

One is very assertive, much bigger and is always hungry (or greedy). She steals food if I leave it out and she eats her sisters food given the chance. She will literally push her out the way and tuck in. We've started to separate them when feeding and locking her outside to eat to stop her pigging out on two meals not one but I can't always watch her.

It's making me really cross and I'm worried the smaller cat is missing out on food.

I started looking online for chipped feeders as I've heard these can work in situations like this.

Any suggestions or recommendations are welcome.

Thanks.

You need to address being cross at a cat who has a different appetite to the smaller one. I also don't think locking her outside is the answer. Reading between the lines you're favouring the smaller cat which is pretty unfair as like people, they have different nature's. If that's off the mark then I apologise.

I asked for help not a moral lecture.

I have no choice other than to lock her out otherwise the other one suffers. I don't think it's damaged her so don't worry. She was on my bed a minute ago, purring and wanting cuddles.

Do you have anything constructive to say?

I have an older cat who would eat all the cat food! She can’t jump up high now so we feed the younger cats up higher.
chip feeders work but are expensive if separating them is working I would continue to do that.

You need micro chip feeders.

I wasn't giving you a moral lecture. I also said if I was off the mark then I apologised. Don't ask for opinions if that's your shite attitude. I'm a vet nurse not an incompetent tit.

Microchip feeders are the answer. One per cat ☺️

They're not cheap but they work and they last years. You could look on eBay or Marketplace too as they often have them second-hand.
