AITAH for explaining to my aunt exactly why our house gets dirty

Ok so this just happened today .

Some context here.
My family and I live in Qatar and we visit our home country every once in a while , my aunt usually would come and do some cleaning up around the house for when we do arrive and then she would stay with us for the remainder of the trip, our house, is fairly big , not like a villa , but it’s not small either.

Here is the thing my aunt has 3 cats , and when she does stay over she brings them with her, no issues there I mean we do understand that she can’t just leave her cats alone, now when her cats are here the balcony has to stay wide open because it contains their litter box, and the front door has to stay wide open the whole day so they can play in the yard .

Now for the real issue
My aunt has been giving passive aggressive comments about how she does everything around the house and how we are so lazy and how filthy we are, let me be clear that this is absolutely not true , we clean everyday , do the bathrooms daily, do the dishes as soon as we use them , and we mop and vacuum almost everyday, the only thing my aunt does around the house is throwing away the trash and putting dishes back in their place, and she’d cook every once in a while .

Today she left to go back to her house , not before throwing yet another comment about how she has to go around cleaning everyday, I was already upset about her comments but what throw me over the edge was when we found out that she had told. My grandma that if it wasn’t for her we would be living in filth, therefore I sent her a message telling her how hurt and upset I am and how her cats shed everywhere and how with keeping the balcony and the front door open , no amount of cleaning can keep up with the dust that accumulates daily, and I sent her picture proof of her cat hair that came out during cleaning.

She sent me a 5 minute voice message explaining how she didn’t mean to and how embarrassed she is.

My sister then told me how in this way we had upset her and there was no need to talk to her and how I should have just let it go.

I’m not sure so aita.
