That would explain it. Two of my relatives (who have both since passed away) use to take in feral cats from around their neighborhood. They had a room in their house just for the cats. But the most they ever had at one time was 14. They wouldโve fainted at the sight of all of those cats.
That would explain it. I had relatives who always had a lot of cats. They had dozens of cats over the years, but the most that they ever had at one time was 15. Theyโd probably faint if they saw all of those cats.
