Hi Christina-have a shufty at the other thread of this nature,peeps have put some great tips on their as i'm sure they will again on here,as other peeps have said cardboard box is a great one,we have sheepskin blankets which are great for kitts,nursing queens and heatpads,we are blessed with a kittening pen which is spacious enough for 2 queens and their litters,cushion floored-easy to clean and safe for if mums want a break and kitts start mooching also Nutra-drops are great if you have a kitt that needs a lift
Good luck with your forthcoming litter
Can't wait to hear about them and of course the pics
