Cat boarding.

Got privvy to the idea when we needed to find boarding for our cat when going on a holiday. Scoped out a few businesses and they were costly, so explored private. All the private ones we visited were simply a largish cage with 3 or so levels, all with litter + bowls within cage. Ranges from $30-40 per night (Australia).

I have a spare room. I looked up Cat Cages and purchased 3 for $150 each. Then I considered what could happen (Vets, abandonment, etc.) and consulted with a lawyer to help write up a contract for customers. (~$1000)

The bare minimum work required is about 20 minutes per day for breakfast, dinner, water top up & scooping the litterbox.

The 3 cages all are booked out about 200 days of the year each for about $18,000 yearly.

Yes I have had 2 people abandon their pets. This was difficult to go through.

edit: I should add - There may be some business hours work required if a cat falls ill and vet trips required.
