Tamagotchi iD-L pets

My Tamagotchi iD-L is a 2-year-old Meloditchi (she just became friend stage this morning). She got a pet today at the donut shop, the pink pet shaped like a blob, I forgot the name, but the pet only shows up when Meloditchi goes places (i.e. the arcade, TamaDepa, etc.). Is this normal? The pet shows up in the pet list, but isn't it lame to have a pet if you almost never see it?

Or maybe there are some criteria before you can keep the pet in your house?

Please help!

Yes, you can only see your pet when you're outside and going places.

You can see your pet inside the house when you connect to another iD L and when they take a picture together. The pets are just added in for decorative purposes.

OK, thanks, but that makes pets seem kind of pointless. Oh well, at least you don't have to pay for them. I'll keep getting the pets every generation anyway.
