One of my cats started insisting on curling up on my left side propped up on my left boob every night when I go to bed some 8-9 months before my diagnoses.
He climbs on places his head over the spot my tumor was found in staring at me and purring intensly.
I just thought it was a weird ned habbit.
Since the lumpectomy I worried how I would deal with him as obviously I could not have the 7.5kg supersized cat on a wound but it never became an issue. The moment I got back from the hospital he climber into bed with me sadly sniffed next to my boob then moved down just below my ribs curlled up and started purring while intensily staring at the wound.... Little guy simply knew.
The other one normally sleeps on my husband's side of the bed but since the surgery he too insists on sleeping by my side just below the 1st boy's spot.
I think they simply know...
