I am one frustrated mommy. I got my new baby Rose when she was 5 and a half weeks old. I planned on putting her in my prevue 465 cage with my two boys. Intros went perfectly and everything would've been great except one problem...Rose could fit through the cage bars! She was so tiny she could squeeze through the bars easily at her whim. I bought hardware cloth and spent 3 hours fitting it around my entire cage. Well it's been a few weeks so last weekend when Rose was 9 weeks old I was sure she was big enough to not be able to fit through the bars. i didn't want to take all the wire off though and have her get through again. So i took off the amount of wire for the front doors of the cage and left it off for the weekend to see if she would come out. She stayed in the cage for the whole weekend so I thought oh good she must not be able to fit! I took off all the wire that night and put them all in the cage for bedtime. It was about 3:30 am at this time and I was very tired. It was like 15 mins later and I thought I saw a shadow on the wall but then it disappeared. Well sure enough a few minutes later Rosie pops up from under my covers in bed like hey mom! Thanks for opening the cage bars up! That was super helpful! i'm just gonna knock everything off your desk while you sleep! I let her play on my bed for a while until she did eventually end up climbing on my desk where she isn't allowed and then I put her back in the cage and told her to stay there! I went back to bed and 5 mins later guess who's back in my bed again...Rose. This continued a few times and i was like I don't know what I am going to do with you. It was 4 in the morning and it took several hours for me to do that wiring the first time so that wasn't an option and I was also out of zip ties from the first time. So i ended up blocking off the bottom half of the cage since they don't use that except for the litter box anyways and I duct taped the wire back onto the top half of the cage and moved the litterbox upstairs. I didn't get to bed until after 5 am and now they will all be confined to only the top half of their cage until Rose is big enough to take the wire off. I cannot believe that she is now 10 weeks old and still fits through the bars. Yes she is a bit skinny yet but she has grown a lot and Idk how she manages to squeeze through there...the bars are just about an inch wide. How much longer is this going to go on for!? I was told she would for sure not fit by 8 weeks old? Does anyone else have a better estimate? I'm shocked she's even still this tiny to be honest. my boys were so much bigger when I got them and they were probably about 4 months old at the time so it's hard for me to judge. Should I hope for her being big enough to take it off by 12 weeks? She's lucky she's so darn cute cuz man was that frustrating!
