Please help save my babies- they need emergency procedures

Hello all, I'm Andreea Nastase, and I kindly ask for your urgent help!

My cat Astrid (7.5 years) needs emergency x-rays and vet procedures to help save her life. She has severe breathing difficulty and the vets don't know the cause yet, although she had blood tests (which stated her white blood cells are elevated indicating and infection, alergy, inflammation or other conditions) and urine tests done...she suffocates and pants, cannot eat, is very lethargic, and we fear the worst...She is under temporary treatment with different medications, but nothing works yet, as the vet needs more tests.

She is scheduled this Tuesday, the 29th of April, for x-rays and further tests; She also has multiple tooth infections (this is an ongoing issue as she has had previous surgeries and extractions in 2021 / 2022), and the vet recommended surgery as well while she is under anesthesia; however, this will cost around or exceeding £1000, money which I unfortunately don't have at the moment, despite trying to source it.

Besides Astrid, I also have two other pets, Shanti (cat- 8 years) and Happy (dog- 11.5 years).

Happy is also poorly, as we have found a lump on this tail, and we are fearing the worst. He has had a biopsy done, however, this came back as inconclusive, and he needs surgery to determine if it is cancer or not. He needs to have this done as soon as possible, so in case it is cancer, we can catch it at an early stage.

Shanti is developing breathing difficulties as well, although hers are not as severe...yet...We need to have her X-rays done in a matter of weeks, so it doesn't develop into something worse, like her sister.

My beloved pet hedgehog (7 years) crossed the rainbow bridge on the 10th of February due to cancer, which has put a severe dent in my finances and mental health, and that is why I come to you for urgent help.

Please, we are in a desperate situation, and we don't know how we can get the necessary funds to save them and afford the medication following all the procedures.

Every little helps, and we are forever grateful for your kind help and support. You are amazing humans with a great heart. Thank you so much in advance for everything!

I will keep you all posted and will come back with updates and more videos/pictures.
