Feeding
How I Feed Three Cats With Completely Different Needs
The challenge with three cats is that they are not the same cat.
Mango is sixteen pounds, male, and would eat continuously if given the option. Pickles is ten years old, less active than she used to be, and needs fewer calories than she did in her prime. Luna is in the middle — both in terms of size and appetite.
Treating them as a unit and feeding them the same amount of the same food was the approach I started with. It did not work.
The problem with a one-size approach
If you set a portion size for the biggest cat, the smaller cats gain weight. If you set it for the smallest, the bigger cat is underfed and will make this known.
Mango and Pickles have very different daily calorie needs — not because one is healthier than the other, but because of their size difference, age difference, and activity level difference. One number cannot serve both of them.
Calculate per cat, not per household
The shift that made the biggest practical difference was calculating each cat's portion individually, then feeding them in separate spots.
This sounds like more work than it is. Once you have the numbers, the routine is the same — you are just putting different amounts in different places.
The cat food portion calculator lets you calculate the correct portion for each cat based on their individual weight, age, and activity level — run it once per cat and you have the numbers you need.
The food theft problem
Separate calculations are useful only if each cat eats their own portion.
Mango finishes his food in approximately forty-five seconds. He then assesses whether anyone else has left anything unattended.
The solution that worked for us was feeding in different rooms with the doors held slightly shut, then letting them out once everyone had finished. It added about three minutes to the feeding routine. It removed a significant source of mealtime stress.
Microchip feeders: genuinely useful for this problem
If separate rooms during meals is not practical, microchip-activated feeders are worth considering. They open only for the registered cat's microchip, which means Mango physically cannot eat Pickles' food regardless of how determined he is.
They are an upfront cost but they solved the portion problem cleanly. Pickles gets her appropriate amount, Mango gets his, and I am not refereeing mealtime.
Adjusting over time
Cats' needs change as they age. Pickles now needs a different amount than she did two years ago. Mango's weight fluctuates slightly and I adjust his portions accordingly.
Doing individual calculations per cat makes it easier to adjust one cat's amount without disrupting the whole feeding setup. Change Pickles' portion size without touching Mango's, and the routine stays intact.
It took a while to get the three-cat system working smoothly. Now it runs on autopilot.
