Caution LONG story. 2 days ago I was fed up with my younger sister, who in theory she is suppose to help care for the guinea pigs ( One was her’s and the other is mine, I treat them equally.), but she lacked off her duty, by lacked off I mean did NOTHING with them unless her or her friends wanted to play with them. At first it didn’t bother me, but one time I was done because I was put up with her neglect with the girls ( Ok you will understand and if my sister didn’t do something for them I did it so the girls had nothing effected on them.) One time I let this slide, it was the night before my sister’s birthday and she had her first sleepover at our house with a friend. They were playing with the girls, I was busy with a project that I was very focused on. So I left the room, then they left, I went back later ( They are upstairs with the stuff I worked on the project. It was there way before the girls.) the girls were still in the play pen, with no food or water and one hidey. I was gone for a little bit, I was mad, but I didn’t want to make a deal in front of the friend ( Very nice and polite kid, mature for her age.) and she is know to make a fit out of little things so I didn’t say anything and put the girls back. I was triggered that I was paying for everything( We made a deal with our dad that we would pay for the toys and the cage and extras, like me buying fleece for them, and saving my money at the time for our current cage.) and she didn’t pay for anything, and didn’t mess with them, also I did all the work. She also got a puppy, so she didn’t do anything with the girls and slacked off a bit with the super hyper puppy, who almost got the girls but they are ok and not my sister’s fault but that is another short story. Another time months before this I had a bad accident and I could care or access to where the girls were ( I HATED it.) she complained that she had to do all the work and was overreacting( I didn’t complain before this.) Also the girls didn’t have the fleece they loved because my family didn’t want to clean it( They did a whole bunch of work to make their area nice, the bedding was care fresh so they were good.) so for one moment she felt how I felt. ( Lucky for me I was able to get up their so I could feed them but couldn’t clean the cage, I was pushing myself and if I did anything wrong I would have to have surgery for the second time.) So my parents told her that she had to pay up or the girls were completely mine. Months passed and it slipped. So I was feeding them and cleaning their 2x6 cage, and 2 days ago I told her 20 minutes before I cleaned the cage, and told her nicely that I need her help with the cage ( I wanted her help, at this time the puppy got better.) Next thing after starting and waiting for her, she was going swimming and said she would help after she swam, I was in the middle of the process, which means the bedding was out. I complained to my dad for a second and continued my work, finished, parents called me to come to them and told me that the girls were mine. So after this crazy event I had to share my personal experience and why my sister so lucky to have me, even though I annoy her a lot. That you should be 100% ready to take over your child’s responsibility when they are caring for an animal. Sorry for the long story.
