Intruders punishment Part 2 🦊💧🎈 - So embarrassing being a giant loud, creaky, taut and continuously growing water balloon! Even the restraining arm broke their so huge. They should have thought twice before sneaking in. Sounds like the guards are on the way and not too far from their foxy intruder.

Intruders punishment 🦊💧🎈 - This factory's security system might be a littttle overkill if you ask me! What will end up happening to the poor fox fellow when and IF it deactivates? Who knows.

Cheddar was just laying down when his sister, Chamomile, came in and just pinned him down to groom him. I know she's just trying to rile him up to play, but she always acts like he's the instigator when he pounces back. X3

Cheddar is usually very photogenic, unless he's sleepy. His eyes stop working right when he's sleepy.

We've been keeping a heater running in our bedroom since the temp has been below freezing the past few days, and its slightly pointed towards my chair. Cheddar has decided that it is now his favorite spot to relax if I'm not there.
Why is he all scrunched on himself like that, your hind foot is not an effective cushion sir.

Both my babies are sharing space together~ Usually Cammy would lay on the hammock downstairs while Cheddar lays in this one.

After Cheddar's surgery we set up a heating pad under a towel for him to have somewhere warm to relax his body, but Cammy continued to bully him out of the way and took the spot for herself the little brat.

Kirk (Balloon in Training) @kirkyeen.bsky.social · 10/10/2025
Cammy's been so nice to her brother since he came home from the vet. They used to sit like this all the time as kittens, but they stopped once they got to big to sit together. It's sweet to see them like this again.

Kirk (Balloon in Training) @kirkyeen.bsky.social · 09/10/2025
The poor boy got neutered recently, so he has to wear a cone to keep him from licking. However, he's too clever for his own good, so we had to tie the cone to his harness so he can't get it off.

Ah yes, the boneless cat loaf, a truly graceful species of unending adorableness.
