Live-In Care: The Best Choice for Your Pets

At Happy at Home Pet Care, we provide professional live-in sitting so your dogs and cats remain calm in their familiar environment — no kennels, no stress, just happy pets in their own space.

We specialise in sits of two nights or longer and regularly care for pets with special needs, including medication administration and anxiety-aware routines. Because we work remotely on site, your pets enjoy a genuinely consistent presence.

Founded and operated by Marcus Watts, Happy at Home brings veterinary-adjacent experience alongside years of trusted sits across London and abroad — from lively Labradors in Seville to farm animals and horses on expeditions in Argentina.

We treat your home with the utmost respect — security-conscious, tidy, and thoughtful. Plants watered, post collected, updates sent. Calm pets, a cared-for home, and peace of mind while you’re away.

Don't just take our word for it—here's what happy pet owners have to say about their experience.

"Marcus was so kind and patient with both Zoe & me. :) He came out of his way to do a meet & greet and talk with us first, which is so important when someone's staying in your home. He was patient and listened with intention as I gave him lots of instructions for my old girl. It was clear Zoe was really comfortable and happy with him when we met but also when I got home. She's old and had some accidents and he handled them with kindness and calmness and let me know what was going on the whole time. He also left my apartment clean, stripped the sheets, etc which was so nice. Would definitely work with him again!"

"Marcus was from the start professional and caring. We had never used a dog/house sitter before Marcus and after meeting him he gave us great assurance. We were away abroad for a week and received daily communication with photos - In his communication he showed his understanding of our 13 year old Lurcher who is not always straightforward- he easily adapted to her routine or lack of!!! We returned to a very calm happy Elsa and the house was absolutely immaculate!! I thoroughly recommend Marcus; in fact I have already booked him for another week the end of this month. It's such a relief to know Elsa will be well looked after especially as she's an elderly dog that needs someone like Marcus - mature and capable."

"Marcus provided excellent care for our dog during our time away. He was punctual, reliable, and handled all responsibilities with care & professionalism. Gracielo was well looked after and returned home calm and content. We were pleased with the overall service and would be happy to use his services again in the future."

"This was our first time using Rover. Marcus was polite and respectful to us and our home and more importantly calm and caring to our nervy Maisie. Our evening was much more relaxed knowing Maisie was being cared for"
