Welcome to the forum, @pixiefae!
I would like to offer my sincere condolences on your loss of Poppy. Most of us here know the pain of losing a furry loved one, and it's always very difficult to say the least.
On that note, I would also like to say that your new girls are absolutely adorable! I LOVE Pippa's scruffy little nose, and Millie's ears are just too adorable, the way they stick out like that!
Again, welcome! Do take the time to read the links that @bpatters provided, there is a lot of useful information in them.
