We have a house guest for 3 weeks while DS1 and DIL are on vacation. Rex their cat has been a regular guest in our house over the years, but not for a long period of time without his masters. He was really grumpy the first couple of days. Now it’s all normal and Rex and Zappa is playing, testing each others traveling bag and Rex is giving Gizmo a friendly groom. They look after each other outside too. It is really sweet to see.
Hugs from Nancy
