We thought we’d provide you with an update on Costco. We’ve renamed him Fenrir, but we call him ‘Fen’. He’s a cuddle monster extraordinaire and hates being left alone (even if you’re showering or going to the bathroom).

The first night he was very courageous, and it was clear he didn’t want to be left in his ‘safe room’ alone – not even for a minute. After three days of listening to him scream non-stop every time we left him in the room, we finally decided to let him have what he wanted. He strutted around like he owned the place, immediately.

Some things have caused him minor concern:

  1. The litter robot (he likes to investigate while it’s cleaning): He’s been a great boy, and uses it even though he’s a little scared of it
  2. His inability to break into the automatic food dispenser, which we got because he’s seemingly constantly ravenous
  3. Our 85 lb dog, Ripley: Ripley is very gentle but terrified of Fen, and Fen takes full advantage of that power by chasing her down the hallway and blocking her from coming down/up the stairs

Overall, Fen is not shy and he tends to face his fears head-on. We put a collar on him day 1 – and he didn’t seem to mind at all. This weekend we will try trimming his nails, but I don’t suspect we’ll have any issues. He loves playing, and has a few toys he hides around the house so that he can keep himself occupied while we sleep. He uses his cat scratch post, has a favourite blanket, sits in his window seat, and tries to eat every single thing he can get his paws on.

He shows a lot of interest in the doors to the outside, so we still put him in his room when we come and go- and when he needs a time-out from terrorizing the dog.

Every day we see improvement in how Ripley and Fen interact as well, so I am confident they will be friends soon enough. Or at least, confident that the dog will feel ‘safe’ enough to walk down the hallway at the same time as the cat!!

Thanks again for everything you did for Costco. He’s been a great addition to our family. We attach some pictures, in the hopes it makes you smile today.
