Hi claire,
Honestly everything you are thinking iand experiencing is normal, she is just a baby honestly. The piddling with the cat could be purely excitment.
She is even a bit young for out walking too much 5-10 mins is enough. Generally paly around the house and yard is enough till they are older. They can get a bit of mixed up thinking the yard is where they piddle when out on the lead. She will learn honestly. What you are seeing is all what we all see and do.
I personally am not fussed on the pad thing but everyone does it differently. I always take outside.
At her age it is wise to restrict her free running around everywhere in the house unless you are not busy and can keep one eye on her , this will limit the accidents.
Mines have all been the same. She will learn. I think it is difficult when trying to train them not to forget they are just little puppies and do remarkably well at such an age.
Hope this reassures you a little.
Pam
