First, I would like to thank the creator(s) of this site. I have been reading and reading the information for the last 2 weeks and have learned a lot.
I just register to post my questions. Pls allow me give you some background info so you know why I am asking for help.
My brother and I want to have a cat for a long time. But Dad does not like animal and thinks we should not spend a dime on "those things". That was fine until the "alien" came and took over me (i.e. I become a teenager). After many arguments/outbursts, finally mom step in and asked dad: "when did we start teaching our kids not to do something because it is expensive or it is too much work?" Good one, right? that is how I got my cat. Somehow, my cat brought a different side of me out. Even dad noticed that. Mom told him cats chased the "alien" out. So, that is how we got away with getting another cat for my brother when Dad was out of town! We LOVE OUR CATS!!
My brother and I take care the cats- grooming, food/water and clean their litter boxes (we have 2 boxes because dad insisted on locking them up when we are not home, so, we set up a second box in the guest room). We pay for litter, food, scratching pole etc.etc. Mom will pay for vet bills. So, we operate in a low budget ($30/month allowance + additional work beyond chores for extra money.) Luckily, my brother won a few essay contests and I will have a summer job.
Before you think I am lazy and got myself a automatic litter box, let me explain. I won at regional and will be leaving for a week to comepte at the international fair (It is unlikely I will win, but it will be a good experience). I asked mom to come with me. It will not be fair for my brother to do all litter box duty, especially during school days (he is very responsible but he is only 12). We are determined not to ask dad to help (he is very grumpy with any cat-related activities or expenses). So, my brother paid 1/6 and I paid 1/3 while mom supplement the other 1/2 (because she wants to go with me in peace). In June, I will be gone for 10 days for the other side of my brain (I am a violinsit) and mom is coming with me too. Then in July, I will be gone to present my project in a different place. So, I got to make the SF works well enough until Aug, at that time, we may put the box away or sell it or...(we can't afford the cartridge!)
I have SF for a week, this is what I did so far. Set up on Sat, scooped out the poop and added crystal on Monday and Thursday. To line the box without spending more money, I took my desk protector (pls don't tell Dad) and cut to fit including the sides, execpt the part behind the rake. I just did a major clean up today and dumped 1/3 crystal out and replace with new one. So far, it is working but I don't know how long the desk protector will last.
My questions are :
1) will shelf-lining sheet work to protect the box? I checked out the price, I can get a roll for about $5 in Target.
2) we brought a box of "self-adhesive laminating sheet" to protect the sofa when the cats were scratching and still have some left, do you think that will work to line the cartridge?
3) do you think I can cut the cost by just scoop out some crystal and add some new one every few days (i.e. without completely replace all crystal, which is so expensive compare to the clumping litter)
Anything else you can suggest. I got to make the SF / cardboard cartridge last- with as little money spent as possible until Aug
Thanks
p.s.I don't know how to get the coroplast-I can't drive yet and don't have a way to order from internet.
