How To Get Two Cats From Gertrude OSRS

Mastering the Old School RuneScape feline replication mechanic requires balancing inventory state, kitten aging timers, and quest completion milestones to maintain two active cats simultaneously. By bypassing standard single-pet restrictions through the misuse of kittens, a seasoned adventurer can farm Death Runes efficiently or secure extra overgrown cats for Karamja store selling.

Pre-Quest and Item Acquisition Planning

Before embarking on the process of duplicating your feline companion in Old School RuneScape, you must evaluate your current inventory management, quest progress, and currency reserves. The primary technical constraint of the engine dictates that a player can only possess one fully grown cat at a time, but loopholes involving kittens and the Gertrude's Cat quest mechanics allow for a dual-pet setup.

• Essential Gear and Currency: Exactly 100 coins for purchasing a kitten from Gertrude, an amulet of cats (optional, but accelerates rat-catching speed), and food to sustain your felines during their growth cycle.
• Mandatory Prerequisite Knowledge: You must have completed the Gertrude's Cat quest. Furthermore, you cannot have a fully grown cat or an overgrown cat in your bank or inventory when attempting to claim a second kitten from Gertrude, as her dialogue triggers a security check against active adult cats.
• Time and Resource Benchmarks: Raising a kitten into a full cat takes approximately three hours of active in-game time. Feeding and interacting with the kitten every twenty to thirty minutes prevents it from running away or reverting to a previous state.

Step-by-Step Two-Cat Acquisition Workflow

Step 1: Secure Your First Feline and Grow It

1. Complete the Gertrude's Cat quest by speaking to Gertrude, finding her cat Fluff in the Lumberyard, and returning her kittens (Fluff's kittens) to her.
2. Purchase a single kitten from Gertrude for 100 coins if you do not already own one. Feed it cooked karambwanji, raw/cooked fish, or milk regularly.
3. Allow the kitten to transition into a fully grown cat after accumulating three hours of game time. Ensure you feed it consistently so it does not escape.
4. Once your cat is fully grown, keep it in your inventory or follow-mode slot.

Warning: Do not let your cat become an overgrown cat yet, or you will disrupt the timing windows required to safely claim a second kitten without triggering the quest's inventory restrictions.

Step 2: Store the First Cat and Purchase the Second

1. Deposit your fully grown cat into your POH (Player Owned House) Menagerie using a cat crate, or place it inside your bank if you do not have a Menagerie constructed.
2. Verify that your inventory, bank, and house contain zero fully grown cats, though you may still have an overgrown cat stored away (it is safest to have no adult cats active anywhere).
3. Travel back to Gertrude's house west of Varrock and initiate dialogue with her while having 100 coins in your inventory.
4. Purchase a second kitten from Gertrude. Because your first cat is safely tucked away in a bank or Menagerie container, the game engine registers your inventory and active slots as "cat-free," allowing the transaction to complete successfully.

Pro-Tip: Make sure you do not have your first cat following you outside while you speak to Gertrude, or she will scold you for already owning a feline and refuse to sell you another.

Step 3: Grow the Second Cat While Managing the First

1. Take your newly acquired second kitten out into the world and begin feeding and petting it to start its three-hour growth timer.
2. Retrieve your first cat from the bank or Menagerie and set it to follow you or place it in your inventory.
3. Feed both felines simultaneously. You must ensure that the younger kitten receives adequate attention to prevent it from running away while you engage in activities like Slayer or questing.
4. Allow the second kitten to grow into a normal, fully grown cat while keeping the first cat at its current growth stage.

Feline Growth Stages and Technical Parameters

Troubleshooting Dual-Cat Management Failures

Gertrude Refuses to Sell Another Kitten

• Root Cause: The game engine detects a fully grown or overgrown cat in your active inventory or following you, or you failed to deposit your first cat into the bank or Menagerie correctly.
• Actionable Fix: Open your bank and check your POH Menagerie carefully. Ensure all adult felines are completely stowed away, and verify your character has no active follower before speaking to Gertrude again.

Kitten Runs Away While Multitasking

• Root Cause: The kitten went un-fed or un-stroked for more than 45 continuous minutes of game time, causing the abandonment timer to trigger.
• Actionable Fix: Always keep raw fish or cooked karambwanji in your active inventory slots when training combat near banks, and check your chat box warnings for messages indicating your kitten is hungry or feeling neglected.

Unable to Store Cat in Menagerie

• Root Cause: Your Construction level is too low to build a Cat Costume Room or a Pet house space, or you lack the required planks and nails.
• Actionable Fix: Use the bank storage method instead by opening any standard bank interface in RuneScape and depositing the cat directly into a bank tab, bypassing the POH requirement entirely.

Frequently Asked Questions

Can I have three cats at the same time in OSRS?

No, the game engine strictly caps player ownership limits to prevent excessive item generation. You can only hold one kitten and one adult/overgrown cat simultaneously by manipulating storage containers and purchase triggers.

What happens if my kitten runs away while I am raising two cats?

If your kitten runs away, it despawns permanently and cannot be recovered, forcing you to start the process over with Gertrude. Your stored adult cat will remain safe in your bank or Menagerie during this time.

Do both cats catch rats for death runes?

Yes, once both cats reach the fully grown stage, you can use either of them to trade in rat-catching frequency for Death Runes in West Ardougne. However, only active followers can catch pests in your vicinity.

Can I sell both cats to the Brimhaven store?

You can sell overgrown cats to the general store in Brimhaven one at a time for cash. By maintaining two cats and letting both reach the overgrown stage sequentially, you can double your profit margins.
