with deafness, either full or partial though, it may be well worth investing in a cat-proof garden.

My tabby boy Misha is partially deaf (scarring from a severe earmite infestation when he was a kitten in a horrible home) and I keep him purely as an indoor cat with walks on a lead, until our new pen is built (the old one didn't stand up to October storms)

All those dangers of cars, dogs, evil people... are higher if your baby can't hear them coming.

can we have a picture? sounds gorgeous!
