A post script to this thread......
Tomorrow we collect our new cat.
He's a 15 year old cream coloured pedigree British shorthair. We'll be his 4th owners. I don't know about the first; the second discovered her daughter was allergic to him; the third is a friend of my daughter-in-law.
The friend got him about 5 years ago shortly after she married. She wanted a dog but everyone said it was cruel to leave a dog alone all day while she was at work, so she adopted Leo. Then she got her dog, a springer spaniel from, of all place, Romania. The poor thing had to spend 6 months in quarantine and now has attachment issues. Then she had a baby who is now a few months old. The cat was being ignored in favour of the dog and baby so she decided it was unfair on him so he needed a new home. We went to see him today and he's lovely.
Our other son, Dylan's owner, is still apologising for us having to watch Dylan's downward spiral so hopefully our getting another cat will reassure him we haven't been put off cats.
