Hi all, sorry in advance for the long thread! About 6 months ago I purchased two male rats and noticed that one was picking on the other and he was becoming quite depressed. To solve this I decided to purchase two more male rats about 2 months ago, this went great at first and they immediately all bonded; until I realised that one of them was infact a female. By this time I’d already fell in love with her and planned to get her desexed but unfortunatly no one in my state would do it (I live in Australia). I’ve decided to let her birth her litter and then seperate them and keep a few of the females for her company. As this is my first time having a female give birth I could really do with some help. My first question is how can I tell that she’s actually pregnant? I’ve heard that pregnancy lasts around 3 weeks but as she’s been living with the males where I got her from her whole life shouldn’t she have already given birth by now? I’ve noticed within the last few days that she’s become extremely round but her nipples still arent showing, can anyone estimate when she will birth? My other concern is whether her age is going to cause any complications, she’s currently around 10 weeks old. Thirdly, should I put her on a special diet? I’ve heard to increase her protein allowance so I have added a few pieces of kitten kibble to her usual feed, is this okay? Finally, what size would you recommend her and her kits seperate nesting enclosure to be? I’m currently using a 54 litre tub filled with torn up old tshirts and toilet paper. Thankyou so much for the help!!
