Pen/segragation

Pick my pup up in 2 weeks, me and the OH have been trying to figure out what we are going to do while we are at work. I have an alcove in the kitchen about 180cm x 100cm which will be the area for the pup with cage, toys and food/water. I am struggling to find a gate wide enough to put up so was thinking along the lines of buying a pen and either building it as a pen or screwing it into the wall at each end.

Was also contemplating just putting a baby gate on the kitchen door but I have a 2 year old cat and his litter and food/water are in the kitchen. Would it be un advisable to leave the puppy and cat together alone where they have to spend time in the same room for a period of time?

Any advice/suggestions welcome.

No i wouldnt leave an adult cat and pup that young alone together until you can trust the cat enough. Took me a few months till the cat accepted the newbie to the house.

Find the best space possible for the pup remove any hazards .inteoduce the dog to the cat slowly with on lead introductions .

I would not let the cat and pup together. I would make sure they are seperated entirely, cause cats really are evil.
