This Level is all about sliding your columns and not wasting moves!
Remember that in order for a level to slide it must be all one color...
and most importantly, the bottom block in that column should not have one of the same color directly to it's right!
It does not matter if any other of the same color is beside the column, as long as that bottom block does not have the same color to it's right (this will prevent the slide)
Drop the Pet, (don't waste moves lowering it, this will happen anyway) then slide it to the center of the game
Here, the same color blocks, line blasters and bombs will drop
One of these will open the pet carrier
Don't waste moves opening it purposely, as you work on sliding the columns it will open anyway via one of the things that drop in the center
Continue sliding until the Pet is free, then do the same again for Pet two...good luck!
