They are both adorable. Barclay looks a lot like my Ripley in the face.

As for Pumpkin's potty habits, you really should take her to a vet to see if she has a urinary infection. They will often pee outside the litter box when they have an infection - probably their way of telling us they feel bad. If she isn't sick then you need to try to figure out what has caused her behavior change. Has something changed in your house like a new pet, company visiting or maybe even new furniture, flooring or something like that.

There are many people here who are much more experienced with this than me but at least this might get you started.

Good luck!
