I sympathize with the girlfriend who finds sharing the bedroom with the cat strange. My husband felt the same way. Thought I was spoiling the animals. I introduced the first cat and now we've moved up to one cat, four dogs, and a bigger bed. Life moves on. Today's purrs may be exactly what is needed to mask tomorrow's snores. No arguing in the bedroom, it upsets the dogs. No bad mood can outlast the good morning greetings from the livestock. What looks like an undesirable and perhaps unsanitary practice quickly becomes the habit you can't live without.
