Practical checklist for small Hong Kong flats: caring for your cat around work
Hong Kong homes are small and cats have limited space. To keep them safe and give yourself peace of mind, follow this checklist.
5 minutes before leaving
- Put all cables, medication, and small items in drawers to prevent chewing or accidental ingestion.
- Check that window grilles are secure, especially for village house residents, to prevent cats from jumping out.
- Fill automatic feeders and water fountains, and press the test button to confirm they dispense food and water properly.
- Set out an extra bowl of dry food and a bowl of water as backup in case the machine fails.
- Scoop the litter box once so your cat won't hold in pee or poop because it's too dirty.
When you get home from work
- First check the remaining amount in the automatic feeder to see if your cat has wolfed down all the food.
- Check the litter box—if there's no "output" at all or noticeably less, watch for constipation or urinary blockage.
- Interact with your cat for 10 minutes—use a wand toy or laser pointer to get them running and make up for the day's lack of mental stimulation.
- Observe your cat's behaviour: if they meow constantly, hide, or have a sudden change in appetite, it could be separation anxiety or illness. If no improvement the next day, book a vet appointment.
Working late / overnight trips
- More than 12 hours: immediately WhatsApp a trusted friend or pet sitter to visit and check on the cat, with photo updates.
- More than 24 hours: book a cat hotel or pet sitter directly. Don't think "just leave extra food for a couple of days"—cats need someone to check their physical condition.
Special version for senior/sick cats
- Write daily medication times on a memo stuck to the fridge so the sitter can follow it.
- Prepare a syringe for water so the sitter can hydrate the cat if needed.
- Stick the vet's card behind the front door so the sitter can grab it in an emergency.
Follow these steps and even in a 200 sq ft flat, your cat can be safe and happy while waiting for you to come home.
