<h1>🧭 When Is a Kitten No Longer a Kitten? (And What to Change As They Grow)</h1>
<p>Your once-sleepy, snack-happy kitten is suddenly racing through the house at 2am, leaping onto shelves, and outgrowing their favorite bed. Welcome to adolescence. 🐾</p>
<p>So when does your kitten officially become a cat? And what do you actually need to change as they grow?</p>
<p>This guide breaks down <strong>key age milestones</strong>, when to switch beds, food, and routines — and how to support your cat through their growth spurt (without losing your mind).</p>
<hr>
<h2>📅 Life Stage Milestones</h2>
<ul>
<li>🍼 0–8 weeks: Neonatal</li>
<li>🐾 8–16 weeks: Early kitten</li>
<li>🎯 4–6 months: Juvenile (big growth)</li>
<li>💨 6–12 months: Teenager (agile + independent)</li>
<li>🧠 12+ months: Adult cat — new routines, body, and needs</li>
</ul>
<p>⚠️ Most cats reach full size by 12–18 months. But behavior can mature slower — especially in rescues or shy cats.</p>
<hr>
<h2>🍽️ When to Change Their Food</h2>
<ul>
<li>✅ Start introducing “all life stages” food by 6–8 months</li>
<li>✅ Reduce overall calories once growth slows (12–14 months)</li>
<li>✅ Maintain a <strong>high protein, low carb, moisture-rich diet</strong> as they transition — just feed to condition, not size</li>
</ul>
<p>💡 No need to switch formulas if you’re already feeding Ziwi, Feline Natural, or raw — just adjust amounts.</p>
<hr>
<h2>🛏️ When to Upgrade Their Bed</h2>
<ul>
<li>❌ If they no longer fit in their Donut Bed or cave</li>
<li>✅ If they’re sleeping more stretched out or elevated</li>
<li>✅ If they need a multi-purpose sleep/play solution</li>
</ul>
<h3>Recommended upgrades:</h3>

</ul>
<hr>
<h2>😴 Sleep & Behavior Changes</h2>
<p>As they grow, cats:</p>
<ul>
<li>Sleep slightly less (12–16 hours/day vs 16–20)</li>
<li>Choose higher or more exposed nap spots (vs enclosed caves)</li>
<li>Become more territorial — multiple beds may reduce conflict in multi-cat homes</li>
</ul>
<hr>
<h2>🎯 Enrichment Needs Shift Too</h2>
<ul>
<li>More climbing, jumping, and vertical movement</li>
<li>Require structured play sessions — not just toys tossed on the floor</li>
<li>Still benefit from puzzle feeders, hideouts, and new textures</li>
</ul>
<p>Keep them engaged with:
<ul>
<li>🧠 Felt tunnels or houses</li>
<li>🔁 3-in-1 Cube used for ambush + sleep</li>
<li>🪶 Wand toys + rotating solo toys</li>
</ul></p>

<h2>💬 From Dr. Duncan Houston</h2>
<blockquote>
“Most cats aren’t fully mature until 12–18 months. That’s when routines, diet portions, and sleep spaces should evolve — but slowly. What they need most is consistency with better-fitting tools.”
