Silly ?? about carriers..

My youngest Zoey is well a tall lanky redhead... by lanky i mean about 11.5 inches at the shoulder.. thus she is too tall for her carrier ( it is a soft side that goes to fifteen lbs)... I have a large like up to a brintey spaniel would fit, it is a hard side and used for my older cat but Kandie isnt willing to share ... I would like a soft sie with a view for her.. any suggestions ??? thx in advance

I had a Pet Wheel-Away was good for up to 30 pounds for my large cat.
Soft sided with mesh, has wheels, or converts to a backpack/carseat.
I ordered it from Petco online.
