Arnold und Mister X

Male · Young · 2 years

Arnold was given up to us due to a supposed allergy, although the people didn't even know the cat's gender. The family's child had brought the cat home a few months ago. Since the animal didn't have a name, we named it Arnold. He was intact and in the beginning quite feisty. For the first few days, he wouldn't let us even check if he was a tomcat or a female cat. Now, he has been neutered, vaccinated, and moved into the cattery. And his anger has calmed down. Although he's not yet a snuggly cat, he now allows contact with selected caregivers. We are looking for a home for him in an apartment with a secure balcony for people who won't pressure him and who might also have a nice, existing fellow animal of similar age.

Arnold wurde wegen einer angeblichen Allergie bei uns abgegeben, wobei die Leute nicht einmal das Geschlecht der Katze kannten. Das Kind der Familie hatte die Katze vor einigen Monaten mit nach Hause gebracht. Da das Tier keinen Namen hatte, haben wir es Arnold genannt. Er war unkastriert und in der ersten Zeit ziemlich auf Krawall gebürstet. In den ersten Tagen ließ er uns nicht einmal schauen, ob er ein Kater oder eine Katze war. Mittlerweile ist er kastriert, geimpft und ins Katzenhaus umgezogen. Und seine Wut hat sich auch gelegt. Er ist zwar noch keine Schmusekatze, aber er lässt inzwischen ersten Kontakt zu ausgewählten Pflegerinnen zu. Wir suchen für ihn ein Zuhause in Innenhaltung mit gesichertem Balkon bei Menschen, die ihn nicht bedrängen und die vielleicht auch einen netten, vorhandenen Artgenossen in ähnlichem Alter haben. Update 18.06.: Für Arnold suchten wir ja eigentlich ein Zuhause,in dem bereits ein netter bereits vorhandener Kumpel auf ihn wartet. Das hat Arnold nun selbst in die Pfoten genommen und sich mit einen netten jungen Kater aus seinem Zimmer angefreundet. Die Beiden würden nun gerne zusammen in ein neues Zuhause ziehen.

About Arnold und Mister X

What life with Arnold und Mister X looks like

Arnold und Mister X is a young adult cat waiting at Tierheim Köln in Cologne.

An adult cat usually shows their personality within a week. Give them a quiet room with everything they need (food, water, litter, hiding spot) and let them choose when to explore. Don't force interaction — every cat decides for themselves when a new home counts as home.

🇩🇪Adopting from Germany

German rescues typically require an in-person home visit (Vorkontrolle) or detailed video home check before approving adoption. Animals leave the shelter sterilized, microchipped, and with a valid EU pet passport. Adoption fees usually fall between €250 and €450, covering veterinary preparation.

Frequently asked

Adopting Arnold und Mister X, answered.

How do I contact the shelter about Arnold und Mister X?
Use the phone, email, or website link in the sidebar of this page. Tierheim Köln handles screening and the adoption contract directly — TailHarbor doesn't broker the conversation. When you reach out, mention you saw Arnold und Mister X on TailHarbor so they know which animal you're asking about.
Can I adopt Arnold und Mister X if I live in another country?
Yes, in most cases. Rescues across Europe routinely place animals abroad — Tierheim Köln will tell you what they need (EU pet passport, rabies titer, transport coordination) and whether they handle transport themselves or refer you to a partner. Plan for an extra €100–€350 in transport costs depending on distance.
Is Arnold und Mister X already vetted, vaccinated, and chipped?
Most cats on TailHarbor leave their shelter with sterilization, current vaccinations, microchip ID, and an EU pet passport included in the adoption fee. The vet status on this page reflects what the shelter has reported — ask them directly if you need details on specific vaccines, recent bloodwork, or chronic conditions.
What happens if Arnold und Mister X isn't the right fit?
Every reputable rescue accepts an animal back if the adoption genuinely doesn't work — that's part of the standard contract. Talk it through with Tierheim Köln early rather than rehoming privately; they know Arnold und Mister X and can place them more successfully than a second-hand listing can.
Why does the description sometimes read awkwardly?
TailHarbor translates shelter descriptions into English from the source language (DE). Translation is imperfect — names of streets, donors, and shelter-specific terms occasionally slip through unidiomatically. For the cleanest read, click the source link to see the shelter's original page.
