I don't think I am, I think it's perfectly fair.
I usually clean both the bathroom and shower room. Not because there's any rota, I don't mind it, it needs doing and I'll usually do it whilst he's cleaning somewhere else in the house. I generally clean up after the DTwatCats, as, well, they need looking after and cleaning up after. DP normally feeds them. He's a bit squeamish about these things, but can just about handle removing half a Wood Mouse or a furball from the kitchen floor armed with rubber gloves, several layers of kitchen roll and a shovel doesn't bother me in the slightest other than feeling a bit sorry for the mouse. Dealing with cat poo is that bit beyond him.
However, DP has ignored my 'the DTwatCat has to have grain free cat food'. Again. With the inevitable results over the shower room floor, as she obviously couldn't get to the litter tray quickly enough.
Whilst I usually don't mind cleaning up puddles of shit, coming in from work to find it again after repeatedly telling him she cannot have 'normal' cat food and it not being fair on her, really annoyed me. He'd been in from work himself for about two hours by then and had noticed it enough to tell me that the floor needed cleaning.
I didn't actually refuse to do it - I asked 'When you're the one who bought her food that makes her ill?'
I'm now listening to the sounds of scrubbing, choking and near puking. And thinking it serves him bloody right for not getting her the GF cat food because he didn't want to walk as far as the nearest stockist.
Consequences of actions, innit? He'll be picking up the posh food tomorrow and today, her Royal Guts will be soothed by poached chicken as will the cast iron guts of the Destroyer of Mouses, but it's not his fault the other one now needs a whole new class of catering
But then, he does look a trifle peaky as he's now emerged to get some air.
Nah. I need to stop feeling guilty and enjoy his discomfort, right?
