To never feed my mums cats again?

[CatLadyToddlerMother]

As title says. Been feeding them for the last week as mum and brother are away on holiday. They are away for another 2 weeks (alright for some!).

I was told (not asked) that I was feeding them as my brother doesn’t trust anyone else apparently (he has serious mental health issues which include trust problems) even though a neighbour of mine is a petsitter and would have done mates rates for them I was handed the keys and told to deal with it. My brothers met the sitter but “doesn’t trust her” despite her having all the relevant DBS checks, and also being insured.

I can’t afford to pay the sitter myself so stuck with two cats, one of whom is elderly and vomits regularly. I also have my own cat (whose thankfully not bothered by anything), and am a single mother to a disabled 3 year old (she turns 3 next week). I drive but don’t own a car and mums taken hers on holiday (with my DDs carseat in!) so I’m having to walk down twice a day as the elderly cat of my mums can’t cope with one meal a day as she’ll overeat and vomit. It’s only 15 minutes away but with DD it can take double that and on Nursery days we’re in the complete opposite direction to mums house so it’s taking up to an 2 hours a day just walking there and back.

I am also recovering from the breakdown of my marriage in March (see other thread) and have appointments all over the county for both myself and DD. I am also terrified that the elderly cat (whose must be around 15 now) is going need vets treatment while they’re away - I have insurance for my cat before anyone points out I have a responsibility to my own cat, mum has no insurance for any of the cats and I couldn’t find the money upfront by myself to pay it.

WIBU to tell my mum next year she will need a sitter even if my brother doesn’t trust them? I can’t do this again, it’s messing with DDs routine which is really important to her due to her particular SN.

WRT the vet, mine just billed me when I got home from holiday the one time my cat needed treatment whilst I was away. A friend took him in but didn’t have to pay.
