"Princess Heidi made a special appearance with her consort DebG at Puttin' on the Dog -- the super fundraiser for the Humane Society of Southern Arizona. The Princess was an instant hit wearing her Easter hat from the Pet Fiesta in support of the HOPE Animal Shelter. Everyone wanted a photo of this celebrity, who actively supports exemplary animal causes! Princess Heidi and Suzi were under the loving care of the Nunn Better team while their parents were on an extended world cruise. Although the parents were missed, Princess Heidi and Suzi reveled in the loving attention and care they received."

-Edward H Stephenson, DVM, PhD

"Thank you, Nunn Better! petsitters, for all of the wonderful care you have provided to Bullet over the years. I feel I am able to relax and enjoy my trips more knowing that my cat and home are being well taken care of. I appreciate the personalized attention you give to each pet. I'm glad that Bullet always seems happy when I return and I enjoy reading the nice notes you leave. I highly recommend Nunn Better to all pet owners."

-Emily Richer Shipsey

"Thank you so much for caring for Robie and Jasper while I was on vacation. For the first time since I've owned cats, I didn't have to worry about them while I was gone and could just "live in the moment." They were very happy to see me but weren't mad at me for leaving. Both were happy and healthy, and I know you spoiled them just as I do when I'm here."

-Carol Fecher - Nunn Better Pet Sitter AND Client

"We were referred to Seneca and her pet sitting service back in 2005 by a friend. My husband and I love the convenience of in-home pet sitting, and have been pleased with the care our pets, Sadie (cat) and Jake (dog) have received. Our sitters have been responsible and compassionate, and most of all, Sadie and Jake love them! Seneca and her staff are easy to get in touch with and are attentive to our requests. We would recommend Nunn Better Pet Care in a heartbeat!"

-The Enokis

"As for the Nunn Better service, I cannot say or thank you all (especially Seneca and Carolyn) enough for taking such good care of our guys."

-The Chabots

"Just a note to thank you and the members of NunnBetter for taking such good care of us whenever Mommy decides to go away. (Unfortunately, since she met you, she doesn't stay home as much as she used to.) But we do love all of the people you send to stay with us. They feed us, give us our medications, play with us and give us lots of love and walks and attention. And the best part is that we don't have to go to a kennel. We've heard Mommy say that when emergencies have arisen, she doesn't know what she would have done without you. She's been able to go on vacation and attend to family matters without having to worry about what would happen to us and who could come to care for us. She just calls you. For that we give you lots and lots of slurps and tail wags. We love you."

-Misty, Snip and Peggy Shimberg (as barked to Mommy Myrna-Sue)

"We have used the Nunn Better services on several occasions and each time we have been completely assured our pups are in the best of care! Nunn Better have excellent pre-stay checklists, tracking records depicting what happened during their stay and follow up calls which shows they genuinely care for our pets. We have and will continue to recommend Nunn Better to all of our friends!"

-Bob & Pam Treece

"You and Brittany are AWESOME! Thank you for taking care of my animals. Everything was perfect! I really liked the way that Brittany stacked my mail and newspaper! We loved the daily notes they were so cute!. If you will have us I will keep having you watch our "children". Thank you for not making me feel bad about Dozer the dog with his peeing problems. I haven't had a vacation in years because I didn't want to board the animals. You have made everything so easy!"

-JoAnn & Tom

"Hi Seneca - of course we want to send a testimonial! Your sensitivity and care during those hard times as Bisbee recuperated from surgery gave us peace of mind and confidence to handle a family travel obligation. You genuinely love and care for Bisbee, and he absolutely loves to have you visit. We want in some way to recognize your help and so please use our names as you wish."

-Monica Spigelman

"Thank you so very much for all the time you spent [gathering my pets caregiver information] it was very comforting to know that you care so much. I know my boy is in good hands. Thank you!"

-Elise L

"Thank you so much for the great way that [our pet] was taken care of. I just feel very lucky that you were there for us. Our other pet needed help too and you knew to provide it. We are very grateful [for you]."

-Jill and Jim R.

"[Our pet sitter] Carolyn did a super job with [our pets]. They were happy, well cared for. Carolyn is truly wonderful!"


"Every time we go away we know 'the kids ' are safe and happy with you. It really allows me to let go, knowing that you are taking care of [our pets]. Thanks again for being such an angel."

-Doug & Lila J.

"Thanks so much for all your help with our kids. It was comforting to know that they were in good hands while I was dealing with [matters of importance, out of state]."


"Thanks for being available to me and [my pets] for questions - you guys have always been great. The cats look well taken care of all of the time but this [last] visit required more of your pet sitter, and more of your time & management [than before] is nice to see how well taken care of the cats are in more difficult times rather than just the easy ones. Thanks again."


"Please know how much at ease you wonderful people make our minds during the trips away from home, just knowing that you'll be looking after 'the kids'. And I truly believe the kids appreciate it completely! Thanks so much."

-Elizabeth P.

"Everyone who has pets- this is for you. We hired Nunn Better! to take care of our cats while we were gone for two weeks and they did an awesome job. I would highly recommend them! The house was spotless, everything that I had asked to be taken care of was done and the cats were fat, sassy and happy when we returned. We will definitely use them again. They are very professional, but love animals and took good care of my babies! Several other neighbors use them, and recommended them to us."

-Elizabeth P.

"Just wanted to say big thanks from Steve and I for the wonderful care that was given to [our pet] while we were away. Seriously, you guys are the best we have found in Tucson. I wish it would not have taken us this long to find you all. [Our pet] was a happy camper when we got home thanks to you all. [Our pet sitter] did a fantastic job and we appreciate all the info you guys give us when we are gone. [Our pet's] report card is on the fridge. We are so proud! Blessings to you guys and your business! Tell her [that our pet] misses her already!"

-Ken and Barbara A.

"You are awesome! Thank you so much for all you did.... We were really able to relax knowing you were in charge...My dad hasn't stopped talking about you!"
