Hi, I have a 14 year old cat with CKD and Hyperthyroidism, long story short she's doing OK and has always lived happily as an only cat. Long story short my mother in law has had a stroke and I am having to take in her two senior cats for approximately 6 months whilst she recovers in rehabilitation unit. I'm so worried about the affect this will have on my own cat. Any tips on how to introduce them and to integrate them happily into the family without causing too much stress to either party.
