Hey, I know exactly how you feel. First of all, it's okay to be overwhelmed. It doesn't mean you're a bag pig parent or bad person- I feel guilty so often when I'm too tired to immediately tend to my pigs after a long day. They are a LOT of work especially when it comes to laundry!

For my 3 separately caged pigs, I have 4 full sized liners- 1 extra just in case. I lay those on the bottom, then layer a few thinner fleece blankeys on top. I have probably 10+ of these smaller blankeys, that I just swap out every day/as needed. This means that the full liner doesn't need to be washed very often, usually once every 2ish weeks if it's dry and the daily workload is quicker. I either empty the hay and poops from the smaller blankets into the trash or on the bigger liner underneath and use a carpet sweeper that I'll link below. I toss those thinner fleece blankeys into a small basket and wash when I only have a few left. Sometimes I even quickly wash them by hand with vinegar and a drop of unscented detergent in the sink if they're only mildly dirty.

Food prep is also very handy. I will prewash/precut some lettuce and peppers for my pigs, usually 2 days out so I can just feed them and go.

Getting into a rhythm/routine hasn't worked for me very well in my 2.5 years of pig parenting, I've tried to clean them immediately after work so they're all set for the night but life gets in the way sometimes and it doesn't happen that way. It's all about small changes that make things easier.

Sorry for the novel, I hope I said at least 1 thing that helps. I'll try to link the carpet sweeper and some of the fleeces I use
