Fustrated beyond belief!

I have two cats, I was only supposed to have one and somehow ended up with two. Boomer and Katana, Boomer is great and loving, Katana hides from me and swipes at me if I try to pet her so I just let her do her own thing.
This morning I woke up to find my girls had piled litter and pieces of paper in the corner of the kitchen and using it to potty instead of using their litter box. This is because they pulled the lining of their litter box over the litter and couldn't use it. They also used my dirty clothes. I am frustrated because this is not the first time they've done this.
No matter how I tie the litter liners down they manage to do this and I am close to crying after to clean yet ANOTHER mess.
I don't want to discipline them, and havent yet, because I am unsure if this natural behavior or if I am doing something wrong.
I got them a bigger box and those filter liners because I have severe depression and don't always have the energy to sit and clean out the box so I thought this would help but obviously not.

They also keep knocking over their water bowl. I got them a heavier bowl thinking this would solve it, and it did for a few days then they managed to knock that one too I am almost constantly having to mop up water when I wake up or get home from work. I am at my wit's end!!!

I love my girls and I want to take good care of them but I feel like a failure right now. Its been a long time since I've owned a cat and when I did he was mostly an outside cat so I didn't have to a lot of this stuff with the litter box I don't know what to do, and I am here hoping that I can learn to be better.

From one depressed cat owner to another, know that you're not a failure! Cats often have acute ways of trying to tell you stuff, that even people are super experienced and work with cats on a daily basis have trouble figuring out (there all over this forum!) - and sometimes they're just mischievous. You've given two cats a home, food and love and that's all amazing! The people on this forum are super friendly, I'm sure someone will be along quickly with wealth of advise!

I find usually the first response with litter problems is to maybe ask your vet - usually a cat not using the litter is a sign of something's wrong? Tho it could just be the case that they're not liking the plastic lining. I use plastic lining but apparently my cat is fine with it (he does tend to put quite a few pricks in it with his claws which means when I pull the lining out with the litter I have to immediately put it into another bag to stop it leaking everywhere). I do put quite a lot of litter so it's unlikely my cat ever touches the plastic at the bottom, it's just the edges where he digs at. 

Thanks for your reply, sorry it took me so long to get back. Work is really sucking the energy out of me! Well, I sort of solved the litter problem, I used binder clips to hold down the liner so that they can no longer pull it into the litter box which work pretty effectively except. The parts that I didn't clip down were pulled in. So more clips!
As for the water bowl, I velcroed it down. I woke up early morning to hear them trying to knock it over and much to my delight they were unable.

I do have another issue and would prefer to just have one forum. I have noticed that when one of them, Katana, drinks, she digs her paws while she drinks. And I noticed that she excessively digs in her litter box.
For example, Boomer will poop and the dig a bit and check that she has covered her poop. Katana on the other hand doesn't stop digging for a period of time and she is getting litter and poop all over the floor around the box.
I am beginning to think maybe she has OCD. I have OCD myself (was diagnosed about 5 years ago) but obviously I can't perform CBT on my cat.
I don't know how similar OCD in cats is to OCD in humans but if she does indeed have OCD and it causes anxiety in her it could explain a lot of her behavior.
I won't be able to take her to the vet until next month unfortunately because I am getting slammed with a lot of bills the next two checks (when it rains it pours as they say)
But if anyone has some insight and some tips on hour to help her, it would be much appreciated.
I am glad to report that she did let me put a claiming collar on her without hissing or scratching me, though she was clearly uncomfortable while I was doing it. Its a pretty big improvement from where we started which was me fully expecting her to kill me in my sleep.
Anyways, possible OCD kitty? Pls help

Just out of curiosity, is Boomer a bit more dominant and assertive than Katana? The excessive effort to hide her excrement may be a sign of submission, especially as she seems to be a bit more anxious in general, judging by your description. If it bothers you, and you have the room, then you might invest in a second litterbox in a different location.

The mental image of your cats trying and failing to knock over their water bowl is pretty funny.

I have no doubt that cats can get mentally ill, I mean it makes sense, they have mental health, no? But when I hear people ascribing human mental illnesses to cats, I do wonder how helpful it is, because a. do they actually mean a cat has OCD or are they using the phrase in the incorrect sense (obviously I know you're not), or is it an actual diagnosis. I mean human diagnosis of mental health illnesses has only relatively recently been given the same weight as physical health, so Idk how far behind veterinary sciences are. Anyway that's just be pondering a subject - it doesn't really answer your question as I have no personal experience with cats and their mental health. I do remember this video from Galaxy: 


It's me in every way  

Hmmm, I don't know if Boomer is more dominant, I would say more outgoing. When I first met them, I was a supervisor at Goodwill. 2 of my coworkers and I started feeding them because they were just small kittens who were so skinny their bones were showing.
We all wanted to take at least one of the two in and somehow I ended up with both LOL. As the cats got more and more used to us, Boomer would run up and greet me but Katana would always stay back and seemed very skittish and scared of people where as Boomer, the lil shit, would run up and try and fight you (unless you had food). We started to get worried when there were bigger and meaner cats starting to come around, it reached its tipping point for me when I got a text from my friend and fellow supervisor telling me that Boomer looked kind of roughed up and she was limping. When I went in I went out back to check on Boomer and she hissed at me when I appoarched. The next night I caught her. I tried to catch Katana but she was smarter than the average cat. It took us a week and a half (and practically every humane trap you could imagine) to nab her. And we didn't feed her for a night and then had to use a big fishing net to catch her in and lower her into a kennel. When we caught her she was hissing and growling in the net trying to claw us and once she was in the kennel, complete silence.
When I got home I let her out in the bathroom and left her in there for a night and then let her out to roam my RV. And she was still terrified of me, I would hear her go to play until I laid down but I think we have mostly gotten used to eachother? She freaks out if I reach for her or anything but she will sleep on the bed with me and Boomer (she just doesn't snuggle with us).
I'm not sure how to tell which cat is more dominant? Would getting them spayed help that if that were an issue?

Unfortunately my internet is so poor rn that I can't watch videos :/ but thank you for them, maybe when I use my friend's Wifi I can watch them!

I read up some on Feline OCD and it sounds pretty similar to OCD in humans though I also don't know how far they are in research with that. I do know that have behavior modification medicine but I also read that putting them on sort of a routine helps. I don't feed them on a schedule, I have one of those auto feeders where the food just comes out as they eat. Maybe starting a scheduled meal time will help her (she is also getting pretty fat).
But I think Cross' theory may actually hold a lot of weight.

Also thank you for the card, that is also me

Hey I am new to having cats and I have 2 litter box's made by natures miracle that rake the poop into a container you empty every few days. My mother in law has the traditional litter box and she is always dealing with ripped liners and mess outside the box. I strongly reccomend this electric liter box it continuously cleans itself and the cats are pleased. I've noticed if I wait too long to empty and theres too much poop in there the cats will pull the poop out and fling it around so I think their obsessive about a clean box.
