🇺🇸 American Intervention Programme: 3 Steps to Rebuilding Security
Phase 1: Environmental optimisation (1-4 weeks)
▸ Set up vertical escape spaces: cat trees/wall hangers on each floor
▸ Use Feliway pheromone diffuser (4.8 Amazon rating)
▸ Retain original shelter supplies: old blankets/food bowls preferred to keep
Phase 2: Behaviour modification (4-8 weeks)
▸ Implement positive interaction training: 5-minute feeding interactions 3 times per day
▸ Introduce puzzle feeder: slow down eating while stimulating the mind
▸ Establish ‘safe words’: specific words are followed by a reward (e.g., ‘Good kitty’).
Stage 3: Medical intervention (if necessary)
▸ Veterinary prescription: antidepressants such as fluoxetine (Prozac)
▸ Regular monitoring: routine CBC blood tests every 2 weeks
🧠 Cognitive Misconceptions Correction
❌ Myth: Cats are solitary animals that do not need companionship
💡 Fact: Modern domestic cats need 2 hours of social interaction per day
❌ Myth: Neutering solves all behavioural problems
💡 Fact: Neutering only reduces the probability of marking behaviour by 50%
