Ziggys heart scan

Our cat Ziggy last month had his 1st seziure he had all bloods and was hospitalized, We managed to pay that  bill but then He had another fit sunday the 20th october. Hes been to vets and we need a heart scan to make sure it's not his heart causing the seziures, this covers the scan plus sedation and 1st lots of meds as either way it be heart issue or epilepsy so will know what meds will be for the best. My cats mean so much to us all and so devastated my poor furbaby feel so helpless. Please if anyone would donate would be so grateful
