Sweet Raven is still learning how to navigate the world with his 3 legs. The way he adapts this chair to his comfort is absolutely brilliant. You can see him resting his hips on the back of the chair, like it was made for him.

We are so grateful to be part of Raven’s care. 🐦‍⬛ He is so gentle and so intelligent. Anything we can do on our end to make his vet visits as comfortable and stress free as possible we will happily do. 🫶🏽🐾🐦‍⬛

Want to know how we know our patients are happy? We were working the other day letting our patient Finn walk around our workspace as we were getting his chemo treatment prepped. We saw him patiently standing on the floor scale for praise (and maybe a snack). He knows we love his head tilt and he was bringing it home for us!

Of course he got all the treats he wanted. Even though we had already weighed him that day 😏❤️

Follow us for more dogs and cats with cancer being AWESOME and living their best lives.

✨ 6 Things We Didn’t See Coming in 2025 ✨

1️⃣ The purrito wrap
That a soft, clingy purrito wrap would be released, and become a total game changer for our patients and clients. Who doesn’t love a good swaddle? 😌🐾

2️⃣ Winning a design award
An honor we never expected and are still pinching ourselves over 🏆 thank you for the recognition of our vision! ✨

3️⃣ The bartender next door
A very kind neighbor who checks on us if he sees our lights on after hours, treats our clients like family, and epitomizes why we love our Table Mesa shopping center community so much. ✨

4️⃣ Merch actually being popular!
Stickers, tees, and little Treeline things you genuinely love — we’re still surprised 😌 and love seeing out in the wild!! Keep sending those photos!

5️⃣ Holiday cards from families we haven’t seen in months to years-
When families move on, we truly miss them. Social media has helped us stay connected, but the number of cards with family updates this absolutely warmed our hearts 🤍🥹

✨ An added bonus: growth and recognition -
More patients, more trust, more gratitude than we ever imagined. We are so grateful for the support and trust we have experienced throughout 2025💞. And we’re excited to see the impact we can make in the coming year 🤍
