I know you had been giving ibuprofen. Do you think he still needs ibuprofen? Can you get metacam? It might be more effective. Keep him well hydrated on those meds.
The only vets I know of are: ABC Animal and Bird Clinic, 11930 Hwy 6 South, Sugarland, TX 77498, 281-495-9445, Dr. Fronfield AND Gulf Coast Veterinary Specialists, 8042 Katy Freeway, Houston, TX 77024, 713-693-1111, Dr. Antinoff is no longer there but someone might see wildlife. If not you might see what clinic Dr. Antinoff has moved to.
Because you are in such a dicey state, please call and confirm they won’t seize prior to divulging any personal info.
